If your car has a radio or is pre-wired for one :
Cut the connector wires one at a time from the plug (leav-
61
ing the leads as long as possible) so that you can work with
individual leads. Turn the ignition on to the accessory posi-
tion, 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 pro-
cedure. (The yellow battery lead provides continuous power
to maintain a clock or other functions.)
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 (not supplied speaker)
Identify the car speaker leads. There are two leads for each
speaker, 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 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.
❏ Connect All Leads
Now that you have identified all the wires in the car, you're

ready to begin connecting them to the LCD monitor wires.
The wiring diagram
nections and color coding of the leads.
We strongly recommend that you test the unit before mak-
ing a final installation.
You can set the unit on the floor and make temporary con-
nections to test the unit. Use electrical tape to cover all
exposed wires.
Important: Connect the red power lead last, after you
have made and insulated all other connections.
Ground
Connect the black ground lead of the power connector to
the metal car chassis.
Speakers (not supplied speaker)
Connect the speaker wires. See the wiring diagram for the
proper hookups. Follow the diagram carefully to avoid
damaging the speakers and the stereo unit.
The speakers used must be able to handle more than 45 W
of audio power. If using an optional audio power, the speak-
ers should be able to handle the maximum amplifier output
power. Speakers with low input ratings can be damaged.
Speaker impedance should measure 4–8 Ω, which is typi-
cally marked on most speakers. Lower or higher imped-
ance speakers will affect output and can cause both speak-
er and stereo unit damage.
Caution: Never ground the speaker cords. For exam-
ple, do not use a chassis ground system or a three-wire
speaker common system. Each speaker must be con-
nected separately using parallel insulated wires. If in
doubt about how your car's speakers are wired, please
consult with your nearest professional installer.
Battery
Connect the yellow battery lead to the correct radio wire or
to the battery fuse port on the fuse block.
Equipment
Connect any optional equipment according to the instruc-
tions furnished with the equipment. Read the operating and
installation instructions of any equipment you will connect
to this unit.
Power
Connect the red power lead to the correct car radio wire or
to the appropriate fuse port on the fuse block.
If the LCD monitor functions properly with all these con-
nections made, disconnect the wires and proceed to the
final installation.
