Required Tools
You'll need a screwdriver, a 1.5 volt AA
battery, and the following:
12 V DC TEST ELECTRICAL
BULB TAPE
Identify All Leads
The first step in installation is to identify all the car
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 car has a radio or is pre-wired for one:
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.
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 car power
lead.
If your car 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).
Battery Lead
If your stereo unit has a yellow lead, you will need
to locate the car's battery lead. Otherwise you may
SIDE-CUT
PLIERS
ignore this procedure. (The yellow battery lead
provides continuous power to maintain a clock,
memory storage, or other function.)
If your car 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 car is not wired for an audio unit:
Go to the fuse block and find the fuse port for the
battery which is usually marked BAT.
Speakers
Identify the car speaker leads. There are two leads
for each speaker which are usually color coded.
A handy way to identify the speaker leads and the
speaker they are connected with is to test the leads
using a 1.5 volt 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
antenna, identify the car motor antenna lead by
connecting 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 will hear the antenna motor activate when you
touch the correct wire.
Antenna
The antenna lead is a thick, black wire with a metal
plug at the end.
