The fi rst step in installation is to identify all the car
wires you’ll use when hooking up your LCD monitor.
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.
Identify All Leads
Connect All Leads
Now that you have identifi ed all the wires in the car,
you are ready to begin connecting them to the LCD
monitor wires. The wiring diagram (page 30) shows
the proper connections and color coding of the
leads.
We strongly recommend that you test the unit
before making a fi nal installation.
You can set the unit on the fl oor and make
temporary connections 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.
Power lead
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 connections made, disconnect the wires and
proceed to the fi nal installation.
Battery lead
Connect the yellow battery lead to the correct radio
wire or to the battery fuse port on the fuse block.
Ground lead
Connect the black ground lead of the power
connector to the metal car chassis.
Equipment
Connect any optional equipment according to the
instructions furnished with the equipment. Read
the operating and installation instructions of any
equipment you will connect to this unit.
Final Installation
Lead Connections
Connect all wires, making sure that each connection
is insulated and secure. Bundle all loose wires and
fasten them with tape so they will not fall down
later.
Congratulations! After making a few fi nal checks,
you’re ready to enjoy your new LCD monitor.
Final Checks
1. Make sure that all wires are properly connected
and insulated.
2. Turn on the ignition to check the unit for proper
operation.
If you have diffi culties, consult your nearest
authorized professional installer for assistance.
Caution:
≥
Do not connect the power connector to the
unit until the wiring is completed. 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 fi nd 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 fi nd the fuse port for radio
(RADIO), accessory (ACC), or ignition (IGN).
Battery Lead
If the 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 fi nd the fuse port for the
battery, usually marked BAT.
Dome light lead
The dome light lead connection varies depending on
the type of vehicle. Consult your dealer or service
technician.
Note for connecting the dome lights
(page 30
s
31):
≥
There are two common types of dome light
circuits used, positive or negative switched.
Positive systems supply voltage to the interior
lights to turn them on, negative switched
systems apply ground to illuminate the bulbs.
≥
The dome light lead connection varies
depending on the type of vehicle. Consult your
dealer or service technician.
≥
Both positive and negative switched light
circuits are supported by this unit’s door
switch. If the door switch is not wired correctly,
the dome light will not come on properly.
The polarity differs from one model to another
so be absolutely sure to ask a dealer or service
technician to wire and install the unit.
