NOTE: Some vehicles, (mostly European) have isolated "left" and "right" side parking lights. To connect to the parking
light systems in these vehicles, you must use separate SPDT relays to connect to each side in order to keep them
isolated. Attach the WHITE wire of the system to this point.
BROWN Wire: Negative (-) Door Sense Input Wire
If the vehicle's interior lights are controlled by grounding door pin switches (typical of most GM, Chrysler, and import
vehicles), the Brown negative door sense wire should connect to one of the vehicle's factory door pin switches. In many
cases the factory door pin switches are wired in parallel, making it necessary to connect to only one door switch in order
to detect the opening of all doors. In a few cases this will not be true, making it necessary to connect to the vehicle dome
light, which typically is the intersection point of all doors.
Locate the vehicle's negative door trigger wire in the vehicle's kick panel or underdash. Connect the BROWN wire of the
system to this point.
PURPLE Wire: Positive (+) Door Sense Input Wire
If the vehicle's interior lights are controlled by +12VDC (Positive) door pin switches (typical of most Ford vehicles), the
Purple positive door sense wire should connect to one of the vehicle's factory door pin switches. In many cases the factory
door pin switches are wired in parallel, making it necessary to connect to only one door switch in order to detect the
opening of all doors. In a few cases this will not be true, making it necessary to connect to the vehicle domelight, which
typically is the intersection point of all doors.
Locate the vehicle's positive door trigger wire in the vehicle's kick panel or underdash. Using the appropriate connector,
attach the PURPLE wire of the system to this point.
BLACK Wire: Main System Ground
This is one of the most important wires of the installation. It must be connected properly to a solid chassis ground.
Special care must be taken to locate a clean metal part of the chassis as an attachment point for this wire. Some
installers prefer to locate a sturdy metal bolt under the dashboard or at the kick panel and use it as the attachment point.
If you find a suitable factory bolt that reads ground when tested, attach a ring terminal connector to the Black wire, remove
the bolt, place the ring terminal over the bolt and reinstall it, tightening it securely. If you choose instead to drill your own
mounting hole into the vehicle's chassis, be certain to remove any paint or grease and secure the ring terminal.
BLACK/WHITE Wire: Horn/Siren Output Wire
This wire provides a ground output (300 mA Max.) designed to drive a relay, which in turn can drive either the vehicle's horn
or an optional electronic siren. Depending upon which sounding device you decide to drive, the Black/White output wire
must first be programmed to control either the Horn or the Siren. The factory default setting is for the wire to control the
horn. Please refer to the section titled; "Programming System Features" later on in this manual for the programming
procedure.
To connect this output to drive a vehicle horn, locate the vehicle's horn wire, almost always a negative switched wire,
(typically found among the wires of the steering column), and connect it.
BLACK/WHITE Wire: Horn/Siren Output Wire
This wire provides a ground output (300 mA). To connect this output to drive an optional siren, a relay must be used to
convert the negative output to a positive output. The output wire must be programmed for siren output. Please refer to the
section titled; "Programming System Features" later on in this manual for the programming procedure.
Find a suitable mounting location for the siren and mount it properly. Run the siren's positive wire into the passenger
compartment to the location of the system and connect it to the additional relay.
GREEN/WHITE: Dome Light Supervision Output Wire
This wire provides a 30 second ground output (300 mA Max.) whenever the remote is used to unlock the doors. This
allows for the illumination of the vehicle's interior before entry. It also provides a flashing output that duplicates the parking
light output flash rate whenever the "Panic Mode" is engaged. This wire must be connected to an external relay and wired
to the vehicle's interior entry lighting whenever the optional Interior Illumination feature circuit is desired.
DARK BLUE Wire: Delayed 300mA Pulsed, Channel 2 Output
The Dark Blue wire supplies a 300mA ground pulsed output whenever channel three of the receiver is accessed.
Pressing Button 3 for three seconds will access Channel 2. This is a low current output and must be connected to a relay
to supply power to the trunk release or the circuit you wish to control. Connect the Dark Blue wire to terminal # 86 of a
VF45F11 P&B relay or equivalent. Connect terminal # 85 of the relay to a fused +12VDC source. Connect the common,
normally open, and normally closed contacts of the relay to perform the selected function of Channel 2.

GREEN/BLACK Wire: Immediate, 300mA Duration of Transmit, Channel 3 Output
The Green/Black wire supplies a 300mA switched output whenever Channel 3 of the receiver is accessed. Pressing A
combination of the transmitter Lock/UnLock buttons simultaneously will access Channel 3 and will remain active for as
long as the transmitter button(s) is held. This is a low current output and must be connected to a relay to supply power to
the device you intend to control. Connect Green/Black Trace wire to terminal #86 of a VF45F11 P&B relay or equivalent.
Connect terminal #85 of the relay to a fused + 12 volt source. Connect the common, normally open, and normally closed
contacts of the relay to perform the selected function of the Channel 3 output.
ORANGE Wire: Ground When Armed Output
This wire provides a 300mA ground output when the keyless entry is locked to control the optional starter inhibit relay.
Connect the Orange wire to terminal #86 of a standard SPDT relay. Connect terminal #85 of the relay to an ignition wire
in the vehicle that is +12VDC when the ignition key is turned to the on and start positions and off when the key is in the off
position. Locate and cut the low current starter solenoid wire found at the vehicle's ignition switch harness. This wire will
have +12VDC when the ignition key is moved to the start (crank) position and will have 0 volts in all other key positions.
Connect one side of the cut wire to terminal #87a of the relay. Connect the other side of the cut wire to terminal #30 of the
relay.
DOOR LOCK/UNLOCK CONTROL HARNESS (3PIN White Plug w/3 Wires; RED, GREEN, & RED/BLACK)
The Red and Green Door Lock/Unlock output wires provide either a momentary pulsed ground (-) or a momentary pulsed
+12VDC (+) output for controlling a vehicle's power door lock/unlock circuit. To better understand this, refer to the table
below:

Red/Black
The Red w/Black trace wire will provide a pulsed ground only and will only provide an output when the lock/unlock button
of the transmitter is pressed a second time after a first unlock command was issued. This is used for second step unlock
or all doors unlock in a two step circuit. In this arrangement, Red is used to control the drivers door unlock relay and the
Red/Black will be used to control unlock of all other doors.
3 Wire Ground Switched Signal Step Door Locks
In this application, the red wire provides a ground pulse during arming, or the pulsed ground lock output. Connect the red
wire to the wire that provides a low current ground signal from the factory door lock switch to the factory door lock control relay.
The green wire provides a ground pulse during disarming, or the pulsed ground unlock output. Connect the green wire to the
wire that provides a low current ground signal from the factory door unlock switch to the factory door lock control relay. Red/
Black Not Used.
3 Wire Ground Switched 2 Step Door Locks
In this application, the red wire provides a ground pulse during locking, or the pulsed ground lock output. Connect the red
wire to the wire that provides a low current ground signal from the factory door lock switch to the factory door lock control relay.
The green wire provides the first ground pulse during unlocking, or the drivers door pulsed ground unlock output.
Connect this wire to the drivers door unlock relay that requires a low current ground signal to unlock only the driver's door.
If the vehicle does not have a separate driver's door relay, one will have to be added. Locate the driver's door unlock motor
wire and cut it at a convenient location to allow wiring of an optional relay. Connect the door side of the cut wire to terminal
30 of the optional relay added. Connect the vehicle side of the cut wire to terminal 87a of the optional relay added. Connect
the green wire of the 3 pin harness to terminal 86 of the optional relay added. Connect terminal 85 of the optional relay
added to a fused constant + 12 volt source. Most vehicles door lock/unlock motor legs rest at ground and switch +12 volts
to the door lock/unlock motor legs for operation. If this is the case in the vehicle you are working on, connect the remaining
terminal 87 to a fused + 12 volt source. In the rare instance that the vehicle door lock/unlock motor legs rest at + 12 volts
and switches ground to the door lock/unlock motors, connect the remaining terminal 87 to chassis ground.
The Red/Black wire provides a pulse ground output when the unlock button of the transmitter is pressed a second time
after unlocking the driver's door. Connect the Green/Black wire to the wire that provides a low current ground signal from
the factory door unlock switch to the factory door lock control relay.
3 Wire Positive Switched Door Locks
In this application, the red wire provides a positive pulse during unlocking, or the pulsed + 12 volt unlock output. Connect
the red wire to the wire that provides a low current positive signal from the factory door unlock switch to the factory door lock
control relay.

The green wire provides a positive pulse during locking, or the pulsed + 12 volt lock output. Connect the green wire to the
wire that provides a low current positive signal from the factory door lock switch to the factory door lock control relay.
3 Wire Positive Switched 2 Step Door Locks
The green wire provides a positive pulse during locking, or the pulsed + 12 volt lock output. Connect the green wire to the
wire that provides a low current positive signal from the factory door lock switch to the factory door lock control relay.
The red wire provides a positive pulse during unlocking, or the driver's door pulsed positive unlock output. Connect this
wire to the driver's door unlock relay that requires a low current positive signal to unlock only the driver's door. If the vehicle
does not have a separate driver's door relay, one will have to be added. Locate the driver's door unlock motor wire and cut
it at a convenient location to allow wiring of an optional relay. Connect the door side of the cut wire to terminal 30 of the
optional relay added. Connect the vehicle side of the cut wire to terminal 87a of the optional relay added. Connect the red
wire of the 3 pin harness to terminal 86 of the optional relay added. Connect terminal 85 of the optional relay added to
chassis ground. Most vehicles door lock/unlock motor legs rest at ground and switch +12 volts to the door lock/unlock
motor legs for operation. If this is the case in the vehicle you are working on, connect the remaining terminal 87 to a fused
+ 12 volt source. In the rare instance that the vehicle door lock/unlock motor legs rest at + 12 volts and switches ground
to the door lock/unlock motors, connect the remaining terminal 87 to chassis ground.
The Red/Black wire provides a pulse ground output when the unlock button of the transmitter is pressed a second time
after unlocking the driver's door. Because the vehicle you are working on requires a positive pulse from the factory door
lock switch to the factory door lock control relay, you will have to add a relay to invert the output polarity of this wire. Connect
the Green/Black wire to terminal 86 of the optional added relay. Connect terminals 85 and 87 to a fused
+ 12 volt source. Connect terminal 30 to the low current door unlock wire from the factory door switch to the door unlock
control relay.

To Program These Features:
Entering the Programming Mode involves operating the Ignition Switch and the Valet/Program/Manual Override Switch in
a particular sequence. This sequence is very time dependent; in other words it must be performed quickly in order for you
to enter the mode. This sequence is also only one step different from the Transmitter Programming Mode, so make
certain you perform the sequence properly.
Upon entering the Programming Mode, the system is immediately set to allow adjustment of the First Programmable
Feature. That First feature, "Passive or Active Arming", can then be set ON or OFF by pressing the lock button of the
transmitter. The system confirms that it is set to adjust the First feature by repeatedly flashing the LED once, with a pause
in between each flash. The system will then report how the feature has been set by the number of chirps heard after
pressing the transmitter button. Toggling the Valet/Program/Manual Override Switch once again will advance you to the
Second Programmable Feature, confirmed by a repeating two LED flashes, with a pause in between each flash, etc., etc.
It is important to note that when you first enter the Programming Mode, you are automatically positioned to adjust the First
Programmable Feature and that the Valet/Program/Manual Override Switch allows you to toggle from there through each
of the six more programmable features. However, it will not allow you to return to any feature once you have toggled past
it. Should you accidentally toggle past the feature you wanted to program, you must exit and re-enter the Programming
Mode and then adjust the feature you missed.
It is also important to note that you may toggle past as many programmable features as you wish without having to adjust
them. Each time you toggle forward to a new feature, the horn will chirp the appropriate number of times (1, 2, or 3 times)
to indicate how that feature is currently set, and the LED will flash the appropriate number of times to indicate the number
of the feature (First through Seventh) that you are set to adjust. For example, you might enter the mode and toggle the
Valet/Program/Manual Override Switch 3 times in order to adjust the Fourth programmable feature. The system would
respond with 1 Chirp, and the LED would begin to flash 4 Flashes, pause, and repeat. This has told you that the system is
ready for you to adjust the Fourth programmable feature, and that it is currently programmed for Chirps ON. A single press
of the lock button of the transmitter will cause the system to produce 2 Chirps. This signifies that you have changed the
programming to Chirps OFF. Please follow the programming procedure below, and refer to the list of the Programmable
Features above when programming the system.

COMPLETING THE INSTALLATION:
After you have confirmed the operation of the system, and tested any and all optional features of the system:
1. 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.
2. 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.
3. Check the vehicle's wipers, lights, horn, etc... to insure proper operation.
4. Replace all panels that were removed during installation, and retest the system.
5. Explain the operation of the system and its various features to the end user if available and place the Owner's Manual
on the dashboard for them to find and review.
