THE RANGE EXTENDER ANTENNA:
The range extender antenna provided with this unit allows routing from below the dash board for maximum
operating range. Choose a location above the belt line (dashboard) of the vehicle for best reception.
Special considerations must be made for windshield glass as some newer vehicles utilize a metallic shielded
window glass that will inhibit or restrict RF reception. In these vehicles, route the exposed, (non shielded)
end toward a rear window location for best reception. Secure the exposed end with double stick tape or
instant stick glue. After securing the exposed end of the antenna with the tape or glue, we advise also
securing a section of the antenna cable to a fixed support. This will prevent the antenna from dropping
down in case the double stick tape is exposed to extreme heat which may loosen it's gummed surface.
VALET/PROGRAM/MANUAL OVERRIDE SWITCH :
Select a mounting location that is easily accessible to the operator of the vehicle. It is not necessary to
conceal the switch however concealment is recommended as it offers a higher level of security. The
switch can be mounted to the lower dash panel in the drivers area. Inspect behind the chosen location to
insure that adequate clearance is allowed for the body of the switch, and also that the drill will not penetrate
any existing factory wiring or fluid lines. Drill a 1/4" hole in the desired location and mount the switch by
passing it through the panel from the underside. Secure the switch using the nut, star washer, and on/off
face plate. It is suggested that the switch be oriented to allow the on position to be up toward the driver and
the off position to be down or away from the driver. Route the switch's connector toward the control module.
CONTROL SWITCH:
Select a mounting location known and accessible to the operator of the vehicle. A lower dash panel, kick
panel, or glove box is desirable. Inspect behind the chosen location to insure that adequate clearance is
allowed for the body of the switch, and also that the drill will not penetrate any existing factory wiring or fluid
lines. Drill a 1/4" hole in the desired location and mount the switch by passing it through the panel from the
underside. Secure the switch using the nut, star washer, and on/off face plate. It is suggested that the
switch be oriented to allow the on position to be up toward the driver and the off position to be down or
away from the driver. Route the switch's connector toward the control module. Place the RED rubber boot,
included in the kit, over the switch handle to differentiate this switch from the valet/program switch.
SHOCK SENSOR:
Select a centrally located, solid mounting surface for the shock sensor that will allow consistent operation
from all areas of the vehicle. The selected location must be within 18" of the control module to allow
routing and connecting of the 4 pin harness. Secure the shock sensor to the chosen location using two #8
self taping sheet metal screws. The sensor can also be secured to an existing dash brace using cable tie
straps. Whichever mounting method is used be sure to allow access to the sensitivity adjustment poten-
tiometer for use later in the installation.
STARTER INHIBIT RELAY:
Select a mounting location within 12" of the ignition switch's low current start solenoid wire. Secure the
relay to an existing harness in the chosen location using a cable tie around the relay's wiring harness.
Caution! Do not wire tie the metal bracket to an existing wiring harness as vibration may cause chaffing
and shorting damaging the factory wiring. If an existing harness is not available then secure the
relay's metal mounting tab to an under dash metal brace with a #8 self taping sheet metal screw.
Wire the relay as per the diagram found later in this manual.
The AA-RS20CS is to be used in vehicles with AUTOMATIC TRANSMISSIONS only! Although this
combination Alarm/Remote Start unit is a sophisticated system with many advanced features, IT MUST
NOT be installed into a vehicle with a manual operated transmission. Doing so may result in serious
personal injury and property damage.
IMPORTANT!
DO NOT PLUG THE SIX PIN MAIN POWER HARNESS OR THE MULTI PIN INPUT / OUTPUT HARNESS
INTO THE CONTROL MODULE UNTIL ALL CONNECTIONS TO THE VEHICLE HAVE BEEN MADE.
AFTER SELECTING YOUR TARGET WIRES AS DEFINED BELOW, DISCONNECT THE NEGATIVE
BATTERY CABLE FROM THE VEHICLE BATTERY PRIOR TO MAKING ANY CONNECTIONS.

WIRING THE 6 PIN MAIN POWER HARNESS:
RED w/ WHITE Trace Wire: + 12 volts Battery 1 Source
Connect this wire to a + 12 VDC constant source found at the vehicle's ignition switch using the 30 Amp
fuse and holder provided.
RED Wire: + 12 Volts Battery 2 Source
Connect this wire to a + 12 VDC constant source found at the vehicle's ignition switch using the 30 Amp
fuse and holder provided, but NOT the same vehicle wire as used by the battery 1 source. Most vehicles
have more than one battery source supplying power to the ignition switch. Separate feed wires must be
used for the Red and Red/White wires. If your vehicle does not have two battery feed wires at the ignition
switch then it is possible to connect both wires to the vehicle's battery.
IMPORTANT!
It is the responsibility of the installing technician to determine the load factor of the vehicles electrical
circuits when the vehicle is running and to adequately fuse the two power wires based on that load. If the
vehicle, running under load with the air conditioner, heater blower motor, and accessories exceed 24 Amps
continuous, we recommend that two fuses be used in combination on each power wire as shown below.
For additional information see Tech Update issued 9/30/96.
YELLOW Wire: Starter Output
Careful consideration for the connection of this wire must be made to prevent the vehicle from
starting while in gear. Understanding the difference between a mechanical and an electrical Neutral
Start Switch will allow you to properly identify the circuit and select the correct installation method.
In addition you will realize why the connection of the safety wire is required for all mechanical
switch configurations.
Failure to make this connection properly can result in personal injury and property damage.
In all installations it is the responsibility of the installing technician to test the remote start unit and assure
that the vehicle cannot start via RF control in any gear selection other than park or neutral.
In both mechanical and electrical neutral start switch configurations, the connection of the Yellow wire will
be made to the low current start solenoid wire of the ignition switch harness. This wire will have +12 volts
when the ignition switch is turned to the start (crank) position only. This wire will have 0 volts in all other
ignition switch positions.
NOTE: This wire must be connected to the vehicle side of the starter cut relay (when used). For the
electrical neutral switch configuration, this connection must be made between the starter inhibit
relay, (when used) and the neutral safety switch as shown in the following diagram.
Failure to connect this wire to the ignition switch side of the of the neutral safety switch can result in
personal injury and property damage.
SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS.

Dark Green Wire: (-) Instant Trigger Input
This is the instant on ground trigger input wire. This wire must be connected to the hood and trunk pin
switches previously installed.
Note: This wire will be shunted when remote control channel 2 is accessed, (trunk release). This wire
will remain shunted all the while there is ground present and for 5 seconds after the ground is
removed. This allows the operator to open the trunk via the remote transmitter without having to
first disarm the alarm system. See below for wiring detail.
Hood Pin Switch Detail
Light Blue Wire: Ignition 3 Output
This wire provides a 300mA ground output that becomes active 3 seconds before the Remote Start Unit
initializes, and remains grounded while running plus an additional 4 seconds after the Remote Start Unit
turns off. In all of the applications described below, a relay will be required.
The Light Blue wire can be used to accommodate the following situations:
A. Shock Sensor By Pass:
If there is a Non Plug in Shock Sensor used with the alarm system and it is not shunted during the
Remote Start activation period, then vibration from the running vehicle can cause the alarm to trigger.
In this case, connect the Light Blue Wire to terminal #86 of a external relay. Connect terminal# 85 of
the relay to a fused + 12 volt battery source. Cut the shock sensor trigger wire and connect one end of
the cut wire to terminal #30 and the other end of the cut wire to terminal #87a. Just before the Remote

Start unit is activated, the relay contacts will open, preventing the shock sensor's operation until the
Remote Start unit shuts off.
B. Ignition 3 Output:
Some newer vehicles use a third ignition wire which is required to start and keep the vehicle's engine
running. If this is the case, connect the Light Blue wire to terminal #86 of an external relay. Connect
terminal # 30 & # 85 to a fused + 12 volt battery source rated for a minimum of 25 Amp. Connect
terminal # 87 to the third ignition wire in the vehicle.
C. GM VATS Key Override:
If the vehicle has the General Motors VATS system installed, you will need to by-pass the system while
the vehicle is operating under the control of the Remote Start Unit. To Do This;
1. Measure the resistance of the resistor pellet on the ignition key then select a resistor within 5% of the
key's value from the resistor pack supplied.
2. Locate the pair of VATS wires in the vehicle, usually a pair of thin gauge wires running from the
ignition switch to the VATS control module.
NOTE: These wires are typically White w/ Black trace and Violet w/ Yellow trace, however in later model
Cadillacs, they are run through an orange sleeve, and are either both Black, both Yellow, or both
White wires. Consult the factory service manual for additional information.
3. Connect the Light Blue Wire from the Remote Start Unit to terminal #86 of an external relay. Connect
terminal #85 of the relay to a fused + 12 volt battery source.
4. Cut (#1) wire (as shown), and connect the ignition switch side of the cut wire to terminal #87a of the
relay. Connect the other side of the (#1) wire to terminal #30.
5. Connect the previously selected resistor from terminal #87 to the second (#2) wire (as shown).
NOTE: The above information and following diagram is for the GM VATS system only. For GM PASS
LOCK System you will require the Audiovox AS-PASS II Module.
Green w/ White trace Wire: Entry Illumination Ground Output
This wire provides a 30 second ground output (300 mA Max.) whenever the remote is used to disarm the
alarm or to unlock the doors and provides a continuous pulsed output whenever the alarm is triggered.
This wire should be connected to an external relay, and wired to the vehicles interior entry lighting
whenever the optional Interior Illumination circuit is desired. See below for relay wiring details.

in which they occur will allow you to determine if they are needed for the particular vehicle you are
working on as well as how to use them.
Black w Blue Trace Wire: Pulsed Ground Output Before Start
The Black w/ Blue Trace wire will provide a 300 mA pulsed ground output 3 seconds before the remote
start unit activates. Typical use for this output would be to disarm a factory theft deterrent system to
prevent false triggering of the factory alarm when the remote start unit engages.
Black w/ Light Green Trace Wire: Pulsed Ground Output After Start
The Black w/ Light Green Trace wire will provide a 300ma pulsed ground output after the vehicle is
started under control of the remote start unit. Typically this wire will be used to re-lock the vehicle doors
if the doors unlock automatically when the factory anti-theft system is disarmed.
Black w/ Red Trace Wire: Pulsed Ground Output After Shutdown
The Black w/ Red Trace wire will provide a 300 mA pulsed ground output after the remote start unit shuts
down. This output will occur regardless of whether the circuit times out or is manually terminated.
Typically this output will be used to re-lock the vehicle doors if the doors unlock automatically when the
ignition circuit transitions to off.
Black w/ Yellow Trace Wire: Ground Output During Start (Crank)
The Black w/ Yellow Trace wire will provide a 300 mA ground output while the starter output of the
remote start unit is active. This output can be used to activate the Crank Low/Bulb Test wire found in
some GM vehicles. This wire is also referred to as the ECM wake up wire in some Chrysler vehicles.
NOTE: The outputs above are low current outputs and must be used with a relay if the circuit's
requirement is more than 300 mA.
2 Pin Control Switch: (Red Connector)
The Black & Black w/White Trace wires loaded in the two pin red connector enable the operation of the
Remote Start unit. When the Black w/ White Trace wire is grounded, the remote start unit is operable.
When this wire is open from ground, the remote start is disabled. Route the twin lead Black and
Black w/White Trace wires from the control switch to the remote start unit and plug red two pin connec-
tor into the mating red two pin connector shell of the control module.
4 Pin Shock Sensor: (White Connector)
The Red (+12 volt), Black (ground), Blue (pre-detect) and Green (full trigger when armed) wires loaded
into the white connector shell are the inputs/outputs of the shock sensor. Route the 4 wire harness from
the shock sensor to the remote start control unit and plug the 4 pin white connector into the mating 4 pin
connector shell of the control module. Note: While operating under the control of the remote start unit
12

the shock sensor will be shunted (by-passed). Once the remote start shuts down, the shock sensor will
be re-enabled.
2 Pin LED Harness: (White Connector)
The Red & Blue wires loaded into the two pin mini white connector control the anode and cathode of the
dash mounted LED. Route the twin lead Red and Blue wires from the LED to the remote start control
unit and plug the two pin connector into the mating white mini connector shell of the control module.
2 Pin Valet/Program Switch: (Blue Connector)
The Black & Grey twin lead wires loaded in the two pin blue connector are the ground supply and
program/valet input of the Remote Start unit. When the Grey wire is grounded, under certain conditions,
the unit will enter the valet mode. When the Grey wire is sequentially grounded under other conditions,
the unit will enter the various program modes. Route the twin lead Black and Grey wires from the valet/
Program switch to the remote start unit and plug the two pin connector into the mating blue connector
shell of the control module. Refer to the remote programming, feature programming and function pro-
gramming shown later in this installation guide for operation of the valet/program switch.
2 Pin Door Lock/Unlock Harness: (White Connector)
The Red & Green Door Lock/Unlock output wires provide either a pulsed ground or pulsed + 12 volts to
control the vehicle door lock / unlock circuits. The output of these wires has a maximum switching
capability of 300mA. Many vehicles today have factory door lock relays which can be connected directly
to these outputs, however always confirm that the factory relays in your particular vehicle do not exceed
the rated 300mA output of the units door lock/unlock circuit. Plug the two pin connector of the door lock/
unlock harness into the mating connector shell of the control module. Determine the door lock circuit of
the vehicle you are working on and wire according to the diagrams shown.
3 Wire Ground Switched Door Lock Circuits:

8. Use button 2 on the transmitter to change the selection of the programmable feature. If you are not
sure what the setting for any feature is, press button 1, one time, the parking lights will flash once or
twice indicating the features setting.
NOTE: Once you've entered the program mode DO NOT allow more than 15 seconds to pass between
steps, or the programming mode will be terminated.
Programming Tach Rate:
The AA-RS20CS will learn the tach rate of the vehicle. To learn tach.
1. Start with the programming switch in the Off position.
2. Turn the ignition key to the On position.
3. Flip the valet/program switch On, Off, On, Off, On, then Off.
4. Immediately turn the ignition key Off.
5. Flip the valet/program switch On, then start the vehicle using the key.
6. When the unit senses the tach signal, the parking lights will begin to flash.
7. Flip the valet/program switch Off, The parking lights will turn on for three seconds to indicate that the
learned tach signal is stored and the unit is out of the tach learn mode.
NOTE: If the unit fails to learn tach rate due to an improper tachometer connection or a poor tach
source, the unit will go into a fail-safe mode. While in this mode, the remote start transmitter will
not function and the program switch will stop responding. This will be indicated by the LED
turning on and off with each operation of the program switch. To correct this situation, locate and
connect the Green/Orange wire to the proper tach signal, disconnect the power wire to the
control module, repower the circuit, re-enter and learn the proper tach signal.
Diagnostics:
Enter selectable feature #7 and turn on as described above.
NOTE: Diagnostic mode is a temporary mode. Once you have accessed the diagnostic mode, the unit

will pause for two seconds then begin to flash the last stored shut down code. This code will be
displayed three times in succession, then the unit will automatically exit the diagnostic on mode.
The parking lights will flash a number of times indicating the reason for the last remote start shutdown.
The light flash indications are as follows:
1 Flash
10 or 15 minute run timer expired
Low or no tach signal (RPM)
Positive or negative inhibit wire activation
Control switch moved to the off position
RF shutdown, Remote signal received
High tach signal (RPM)
2 Flashes
3 Flashes
4 Flashes
5 Flashes
6 Flashes
Multi Coil Pack Adaptor: (Optional)
The multi coil pack adaptor is designed for use with vehicles having multiple ignition coils where a single
point tach signal is unavailable.
To use the adaptor, the Green/Black wires must connect to the negative side of the ignition coil(s).
1. For vehicles utilizing independent coils per cylinder, connect the three Green/Black leads to alternate
coils. To achieve optimum performance the coil signals must be evenly distributed. This is accom-
plished by first mapping out the firing order of the engine in groups of as indicated below. Draw a
circle around any of the columns. The Green/Black wires should be connected to the negative (-)
terminal of the respective cylinder number which appears in any of the circles.
2. For vehicles utilizing 2 cylinder firing per coil pack, connect Green/Black to the tach side of each coil
pack. For 8 cylinder, four coil systems, connect to any of the three coils.
3. Connect the Yellow wire to a +12 volt ignition 1 source. This wire will have +12 volts with the ignition
in the on and start position and have 0 volts with the ignition in the off position.
4. Connect the Green wire to the (Green) or (Orange/Green) tach input of the Audiovox remote start
unit.

TESTING YOUR INSTALLATION:
WARNING !! The following procedure must be performed after the installation of an Audiovox Remote
Start Device. It is the responsibility of the installing technician to complete these tests. Failure to test the
unit in the following manner may result in personal injury, property damage, or both.
HOOD PIN SAFETY SHUT DOWN:
The intention of the hood pin safety shut down is to prevent the Remote Start unit from being activated
while a mechanic or vehicle owner is performing normal routine vehicle maintenance.
To test the integrity of this circuit:
1. With the drivers window in the down position, start the vehicle using the RF transmitter.
2. Reach inside the car and pull the hood release.
3. Raise the hood and confirm that the remote start unit shuts down.
If the unit fails this test, recheck your pin switch connection to the Gray/Black wire of the Audiovox
Remote Start Unit.
DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE
OPERATION OF THE HOOD PIN SAFETY SHUT DOWN FEATURE.
MANUAL SHUT DOWN / ENABLE CIRCUIT:
The intent of the manual shut down / enable circuit is to allow the vehicle operator to prevent operation
of the Remote Start Unit regardless of the RF transmitter operation.
To test the integrity of the manual shut down / enable circuit:
1. Place the control switch in the on (Closed To Ground) position.
2. Start the vehicle using the RF transmitter.
3. The vehicle should start and run under the control of the remote start unit.
4. Move the switch to the off (Open From Ground) position, the vehicle should shut off.
If the unit fails this test, recheck your enable switch connection to the Ground and the Black/White wire
of the Audiovox Remote Start Unit. If you have a plug in enable switch, check that the two pin connector
is firmly seated in the mating connector on the control module.
DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE
OPERATION OF THE MANUAL SHUT DOWN / ENABLE FEATURE.
NEUTRAL START SAFETY TEST:
The intent of the neutral start switch is to prevent the vehicle from starting while the gear selector is in
any position other than Park, or Neutral. When installing a Remote Start Device, it is imperative that the
Yellow Starter wire be connected to the ignition switch side of the Neutral Start Switch. Consideration for
the placement of a starter inhibit relay is important as well, and should be connected to the ignition
switch side of the Yellow Start Wire.
To test the integrity of the Neutral Start Safety Circuit:
1. Set the vehicle parking brake.
2. Block the drive wheels to prevent vehicle movement.
3. Temporarily disconnect the Brown/Black positive shut down wire from the vehicle's brake switch.
4. Sitting in the vehicle, start the engine using the vehicle's ignition key.
5. Step on the brake pedal and shift the gear selector into reverse.
6. Allow the transmission to shift. When you feel the engine pull, do not move the gear selector just turn
the ignition switch off. DO NOT attempt to remove the key.
7. Keeping the brake pedal depressed, activate the RF transmitter in an attempt to start the vehicle. The
car should not start.

8. Repeat the above test this time move the gear selector to the drive position. If the unit attempts to
start, failing this test, recheck your Yellow Wire's connection. This wire must be connected to the
ignition switch side of the Neutral Start Switch. If the vehicle you are working on does not have an
Electrical Neutral Safety Switch, it will be necessary to re-configure the Remote Starts Wiring to
accommodate this vehicle. The information concerning the Mechanical Neutral Safety Switch provided
below will help you to determine if the vehicle you are working on has this type of safety switch and
will provide alternate wiring methods to accommodate this situation.
CAUTION!
REMEMBER TO RECONNECT THE BROWN/BLACK WIRE TEMPORARILY
DISCONNECTED IN STEP 3
DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE OPERATION
OF THE NEUTRAL SAFETY START FEATURE.
MECHANICAL NEUTRAL SAFETY SWITCH CONSIDERATIONS:
Mechanical neutral safety switch configurations differ slightly in that they do not offer the same level of
safety when installing a remote start device. Often when the ignition switch is turned off while the gear
selector is in any position other than park or neutral, the mechanical function will not allow the key to be
turned to the start position or be removed from the ignition cylinder. This configuration prevents me-
chanical operation while the vehicle is in gear but offers no consideration for electrical operation. Be-
cause of this potential problem, this installation requires the additional connection of a safety wire from
the remote start device to the vehicle Park/Neutral ECM Input or the vehicle key in sensor. This
connection will prevent remote start operation if the key is left in the ignition switch regardless of the
gear selectors position.
PARK / NEUTRAL ECM INPUT:
The Park / Neutral ECM input is the preferred method of installation. This not only maintains the
integrity of the factory circuit, it is also the easiest to install, providing the vehicle you are working on
has this ECM input.
The installation required for this application (shown below), indicates the slight re-configuration of the
control switch wiring and the addition of a 4000 series diode. Shown is a typical GM Park/Neutral ECM
19

input circuit. To connect the Audiovox remote start unit to the GM Park / Neutral ECM input:
1. Locate the Orange / Black reference wire in the" C2" connector found at the ECM in GM B Body
vehicles or, locate the equivalent reference wire in the vehicle you are installing the Audiovox
Remote Start Unit in.
2. Connect the Cathode, (Striped) end, of a 4000 series diode to this reference wire.
3. Connect the Anode, (Non Striped) end, of the diode to one side of the Remote Starts enable switch.
4. Connect the other side of the enable switch to the Black/White enable input wire of the Remote Start
unit.
The reference diagram below shows a typical GM B Body ECM reference wire and how it is to be
connected to the Remote Start Unit.
KEY IN SENSOR CIRCUITS:
If the vehicle you are working on does not have or you cannot locate the ECM reference wire, there are
two alternatives available. Although not preferred, the vehicle Key In Sensor may be re-configured to
allow a margin of safety and will prevent the vehicle with a Mechanical Neutral Start Switch from starting
in gear.
AUDIOVOX ADVISES THAT YOU MAINTAIN THE FACTORY CIRCUIT WHENEVER POSSIBLE. The
following two circuits may be used only if the above circuit is not available.
NOTE: When completing an installation using either of the following key in sensor circuits, if the operator
inserts the ignition key while the vehicle is running under the control of the Remote Start, the
vehicle will shut down. This must be explained to the operator as it is in contrast to the normal
operation of a vehicle utilizing an electrical neutral start switch and is inconsistent with the
operators manual.
Additional information concerning Key In Sensor methods 1 & 2 are listed below and should be reviewed
before considering either alternative.
Method 1 will allow the safety required for the remote start unit and prevent the vehicle from starting
while in any gear other than Park or Neutral while the key is in the ignition cylinder however, if the key is
left in the ignition switch and the door is left opened, the added relay will be energized causing a 150mA
drain on the battery.
METHOD 1

Method 2 will allow the safety required for the remote start unit and prevent the vehicle from starting
while in any gear other than Park or Neutral while the key is in the ignition cylinder however, the original
factory key in chime module will not alert the owner that the key has been left in the ignition switch. In
addition, this may also effect other warning tones such as the light on reminder.
METHOD 2
These situations should be carefully considered before altering the vehicle's wiring and must be fully
explained to the consumer.
To connect to the key in sensor as shown in method 1:
A. Locate the control wire that connects the drivers door pin switch to the key in sensor switch.
B. Cut this wire and connect the ignition cylinder side to chassis ground.
C. Locate the key in sensor switch wire that connects the chime module to the ignition cylinder .
D. Cut this wire and connect the ignition cylinder side to terminal 30 of a P&B VF45F11 or equivalent relay.
E. Connect the cathode (striped) side of a 4002 series diode to this same wire, and connect the (non
striped) side to the negative shut down safety wire (Gray / Black) of the Audiovox Remote Start Unit.
F. Connect terminal 86 of the relay to a fused +12 volt constant battery source.
G. Connect terminal 87 of the relay to the Chime Module side of the previously cut wire in step D.
H. Connect terminal 85 of the relay to the Drivers Door side of the pin switch wire previously cut in step B.
NOTE: A second 4002 series diode may be required to maintain the integrity of the hood open, shut
down circuit. If this is the case, it must be installed as shown in the diagram above. The anode
(Non Striped) side must be connected to the Gray/Black wire of the Remote Start Unit. The
cathode (Striped) side must be connected to the hood pin switch. If the hood pin switch is also
used for an alarm trigger input, be certain to use the dual diode assembly packaged with the
Audiovox Remote Start Unit as shown in this installation guide. (Page 9)
To connect to the key in sensor circuit as shown for method 2:
A. Locate the control wire that connects the drivers door pin switch to the key in sensor switch.
B. Cut this wire and connect the ignition cylinder side to chassis ground.
C. Locate the key in sensor switch wire that connects the chime module to the ignition cylinder .
D. Cut this wire and connect the ignition cylinder side to the Remote Start Negative Safety Shut down
Wire Gray/Black, using a 4002 series diode as shown above.
NOTE: A second 4002 series diode may be required to maintain the integrity of the hood open, shut
down circuit. If this is the case, it must be installed as shown in the diagram above. The anode
(Non Striped) side must be connected to the Gray/Black wire of the Remote Start Unit. The
cathode (Striped) side must be connected to the hood pin switch. If the hood pin switch is also

used for an alarm trigger input, be certain to use the dual diode assembly packaged with the
Audiovox Remote Start Unit as shown in this installation guide. (Page 9)
AFTER THE CONNECTION OF THE NEUTRAL START SAFETY WIRE AS INDICATED IN ANY OF
THE PREVIOUS ALTERNATE CONFIGURATIONS, THIS CIRCUIT MUST BE TESTED FOR OPERATION.
Retest by following the steps outlined in the NEUTRAL START SAFETY TEST shown in this manual.
COMPLETING THE INSTALLATION:
After you have confirmed the operation of the Audiovox Remote Start unit and tested all the safety
features of the system:
1. If you have not done so already, place the red rubber handle cover over the handle of the control
switch for ease of identification. This will allow your customer to distinguish the Remote Start control
switch from the program switch.
2. Mount the control module up and behind the dash securing it in place with cable ties or screws. Be
certain that the chosen mounting location will not inhibit any of the controls of the vehicle.
3. Securely harness and tie all wiring up and away from all hot and moving parts that they may come in
contact with under the dash board or in the engine compartment areas.
CAUTION: Particularly avoid the area around the steering shaft and column, as wires can wrap around
these mechanisms and impair the safe operation of the vehicle.
4. Apply the Caution Labels supplied with this kit to a conspicuous area in the engine compartment.
Make sure to clean the surface before affixing the label.
5. Check the vehicle's wipers, lights, horn, etc.... to insure proper operation.
6. Replace all panels that were removed during installation, and retest the system.
7. Explain all activated features and safety systems associated with Remote Start Unit installed to the
customer.
