Q Identify All Leads
The first step in installation is to identify all the car
wires you'll 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 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.
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 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 pro-
vides 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 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 one of the speakers if you
are holding a speaker lead.
lf not, keep testing different lead combinations until
you have located all the speaker leads. When you
label them, inciude the speaker location for each.
