the following:

12 V DC

TEST BULB

ELECTRICAL

TAPE

SIDE-CUT

PLIERS

Cut the connector plug off (leaving the leads as long
as possible) so that you can work with individual
leads.

□ Dashboard Specifications

THICKNESS

(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 in

the following order.

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 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.)

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.

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 vehicle speaker leads. There will be two
leads for each speaker, usually color coded.
