Cut the connector wires one at a time from the
plug (leaving the leads as long as possible) so
that you can work with individual leads.
Required Tools
❏
You'll need a screwdriver, a 1.5 volt AA battery
and the following:
12 V DC
TEST BULB
ELECTRICAL SIDE-CUT
TAPE PLIERS
Turn the ignition on to the accessory position, and
ground one lead of the test bulb to the chassis.
Touch the other lead of the test bulb to each of
the exposed wires from the cut radio connector
plug. Touch one wire at a time until you find the
outlet that causes the test bulb to light.

MIN. 3/16" (4.75 mm)
MAX. 7/32" (5.56 mm)
Now turn the ignition off and then on. If the bulb
also turns off and on, that outlet is the vehicle
power lead.
2-3/32" (53 mm)
If your vehicle is not wired for an audio unit:
Go to the fuse block and find the fuse port for
radio (RADIO), accessory (ACC), or ignition
(IGN).
7-5/32" (182mm)
Battery Lead
If your stereo unit has a yellow lead, you will
need to locate the vehicle's battery lead.
Otherwise you may ignore this procedure. (The
yellow battery lead provides continuous power to
maintain a clock, memory storage or other
function.)
Identify All Leads
❏
The first step in installation is to identify all the
vehicle wires you'll use when hooking up your
sound system.
As you identify each wire, we suggest that you
label it using masking tape and a permanent
marker. This will help avoid confusion when
making connections later.
If your vehicle has a radio or is pre-wired for one:
With the ignition and headlights off, identify the
vehicle battery lead by grounding one lead of the
test bulb to the chassis and checking the
remaining exposed wires from the cut radio
connector plug.
Note: Do not connect the power connector to the
stereo unit until you have made all connections.
If there are no plastic caps on the stereo hooking
wires, insulate all exposed leads with electrical
tape until you are ready to use them. Identify the
leads in the following order.
If your vehicle is not wired for an audio unit:
Go to the fuse block and find the fuse port for the
battery, usually marked BAT.
Power Lead
If your vehicle has a radio or is pre-wired for one:
Speakers
Identify the vehicle speaker leads. There will be
two leads for each speaker, usually color coded.
20
Download from Www.Somanuals.com. All Manuals Search And Download.
Installation Guide (continued)
A handy way to identify the speaker leads and
the speaker they connect with is to test the leads
using a 1.5 volt AA battery as follows.
Speakers
Connect the speaker wires. See the wiring
diagram below for the proper hookups. Follow
the diagram carefully to avoid damaging the
speakers and the stereo unit.
Hold one lead against one pole of the battery
and stroke the other lead across the other pole.
You will hear a scraping sound in a speaker if
you are holding a speaker lead.
If not, keep testing different lead combinations
until you have located all the speaker leads.
When you label them, include the speaker
location for each.
The speaker used must be able to handle more
than 37 watts of audio power. If using an
optional audio power, the speakers should be
able to handle the maximum amplifier output
power. Speakers with low input ratings can be
damaged.
Antenna
Speaker impedance should measure 4 - 8 ohms,
which is typically marked on most speakers.
Lower or higher impedance speakers will affect
output and can cause both speaker and stereo
unit damage.
The antenna lead is a thick, black wire with a
metal plug at the end.
Caution: Never ground the speaker cords. For
example, do not use a chassis ground system or
a three-wire speaker common system. Each
speaker must be connected separately using
parallel insulated wires. If in doubt about how
your car's speakers are wired, please consult
with your nearest professional installer.
Connect All Leads
❏
Now that you have identified all the wires in the
vehicle, you’re ready to begin connecting them to
the stereo unit wires. The connection diagram on
Page 26, 27 show the proper connections and
color coding of the leads.
We strongly recommend that you test the unit
before making a final installation.
CORRECT
You can set the unit on the floor and make
temporary connections to test the unit. Use
electrical tape to cover all exposed wires.

Battery
Final Installation
❏
Connect the yellow battery lead to the correct
radio wire or to the battery fuse port on the fuse
block.
Lead Connections
Connect all wires, making sure that each
connection is insulated and secure. Bundle all
loose wires and fasten them with tape so they
won't fall down later. Now insert the stereo unit
into the mounting collar.
Antenna
Connect the antenna by plugging the antenna
lead into the antenna receptacle.
Congratulations! After making a few final checks,
you're ready to enjoy your new auto stereo
system.
Equipment
Connect any optional equipment such as
amplifier, according to the instructions furnished
with the equipment. Keep about 12 inches (30
cm) of distance between the speaker
cords/amplifier unit and the antenna/antenna
extension cord. Read the operating and
installation instructions for any equipment you
will connect to this unit.
Final Checks
❏
1. Make sure that all wires are properly
connected and insulated.
2. Make sure that the stereo unit is securely
held in the mounting collar.
3. Turn on the ignition to check the unit for
proper operation.
Accessory (ACC) Power
Connect the red power lead to the correct
vehicle radio wire or to the appropriate fuse port
on the fuse block.
If you have difficulties, consult your nearest
authorized professional installer for assistance.
If the stereo unit functions properly with all these
connections made, disconnect the wires and
proceed to the final installation.
