Identify All Leads
The first step in installation is to identify all the car
wires you'H use when hooking up your sound sys-
tem.
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 ail connections. If there
are no plastic caps on the stereo hooking wires,
insulate aU exposed leads with electrical tape until
you are ready to use them. identify the ieads in
the following order.
Power ead
If
your car has a radio or is pre-wired for one:
Gut 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.
i~
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 tum the ignition off and then on. If the bulb
also turns off and on, that outlet is the car power
lead.
If your car is not wired tor an audio unit:
Go to the fuse block and find the fuse port for radio
(RADIO), accessory (ACe), or ignition (IGN).
Battery lead
'.
If your stereo unit has a yellow lead, you will need
to locate the car'sbatlery lead. Otherwise you may
ignore this procedure. (The yellow battery lead pro-
vides continuous power. to maiRfaina clock. memo-

!f your car 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
are two
leads
for each speaker which are us any color coded.
A handy way to ide tify the speake leads and the
speaker "'hey are con ected with is to tes'" "'he leads
using a 1.5 V AA battery as follows.
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 one of the speakers 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.
Antenna Motor
If your car is equipped with
an
automatic power an-
tenna, identify the car motor antenna lead by con-
necting one bulb tester lead to the car battery lead
and touching the remaining exposed wires from the
cut radio connector plug one at a time. You wiU
hear the antenna motor activate when you touch the
correct wire.
Antenna
he antenna lead is
a
thick, black wire with
a
metal
plug at the end.
o
Connect AU leads
Now that you have identified aU the wires in the car,
you are ready to begin connecting them to the
stereo unit wires. The wiring diagram (page 52)
shows the proper connections and color coding of
the leads.
We strongly recomme d that you test the unit be-
fore making a final installation.
You can set the unit on the floor and make tempo-
rary connections to test the unit. Use electrical tape
to cover all exposed wires.
