You'll need a screwdriver, a 1.5 volt AA bat¬
tery, and the following:
12 V DC
ELECTRICAL
SIDE-CUT
TEST BULB
TAPE
PLIERS

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 connec¬
tions. 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 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
CQ-DFX77/DFX55/DF66/DF44EUC
light.
Now turn the ignition off and then on. If the
bulb also turns off and on, that outlet is the ve¬
hicle 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. Otherwise
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 re¬
maining exposed wires from the cut radio con¬
nector 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 lo¬
cation for each.
Antenna Motor
If your vehicle is equipped with an automatic
power antenna, identify the vehicle motor an¬
tenna lead by connecting one bulb tester lead
to the vehicle battery lead and touching the re¬
maining exposed wires from the cut radio con¬
nector 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.
