Installation Guide

Identity 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
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, 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 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
antenna, identity 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.
