□ 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
□ Dashboard Specifications
THICKNESS
(53 mm)
□ Identify All Leads
The first Step in installation is to identify all the
vehicle 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:
Cut the connector plug off (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 order 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).
Battery Lead
If your stereo unit has a yellow lead, you will need
to locate the car’s battery lead. Othenwise 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
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.
A handy way to identify the speaker leads and the
speaker they connect 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 a speaker 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 vehicle is equipped with an automatic
power
antenna, identify the vehicle motor
antenna lead by connecting one bulb tester lead
to the vehicle 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.
