□ Required Tools

You’ll need a screwdriver, a 1.5 volt AA battery, and

the following:

12 V DC

TEST BULB

ELECTRICAL

TAPE

SIDE-CUT

PLIERS

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.

□ Dashboard Specifications

THICKNESS

MIN. 3/16" (4.75 mm)

■—rjj:--- MAX. 7/32"

2-3/32" (53 mm

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.

Now turn the ignition off and then on. If the bulb
also turns off and on, that outlet is the vehicle
power lead.

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).

□ Identify All Leads

The first step in installation is to identify all the vehi
cle 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.

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
as follows.

Power Lead

If your vehicle has a radio or is pre-wired for one :

Battery Lead
If your stereo unit has a yellow lead, you will need

to locate the car's battery lead. Otherwise you may

ignore this procedure. (The yellow battery lead pro
vides continuous power to maintain a clock, memo

ry storage, or other function.)

If your vehicle has a radio or is pre-wired for one:

With the ignition and headlights off, identify the car
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.

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.

Speakers

Identify the car speaker leads. There will be two

leads for each speaker, usually color coded.
