3 Cutting the headliner and mounting the bracket
IMPORTANT!
Do NOT start this step until you have inspected the headliner, roof beam, and all other essential
!
areas to verify the installation can be successfully completed. It is your responsibility to ensure
the installation is safe, secure and appropriate for the vehicle.
You will need to cut the headliner to create a path for the cables and mounting bracket. The following steps will
guide you through this process
STEP 1: LOCATE THE MOUNTING POSITION
Using masking tape or chalk, mark the side-to-side centerline of the headliner. Next, mark forward-to-aft position, which
locates the display as far forward as possible, but rearward of the front seats.
STEP 2: CHECK THE CONTOURS
Using the Cutout template located in the mounting position from Step 1, check the
headliner for contours. Contours in the headliner will require modifi cations to the
trim ring. For extreme contours, you may need to use an optional tall trim ring. Mod-
ifi ng the trim ring to follow the contours is required to avoid problems ranging from
no disc eject to poor latch retention.
STEP 3: CUT THE HEADLINER
Once you are satisfi ed with the location, using the Cutout template, cut the open-
ings for the cables and four mounting screws. You may also need to cut an opening
to slide the mounting bracket through the headliner.
IMPORTANT!
!
Do NOT cut away too much of the headliner. This creates a direct heat path, which can lead
to overheating the system during very hot days.
CAUTION!
Make sure that the screws you use to mount the bracket and/or the main unit are NOT too
long! If the screws you select are too long, you will damage the roof of the vehicle. Take

4 Routing the harnesses and making the wiring connections
STOP
You will need to route the harnesses above the headliner from the system to your selected connection points.
The following steps will guide you through this process.
STEP 1: LOCATE POWER CONNECTION POINTS
This system requires a minimum of 12V (+) Constant, 12V (+) ACC Switched and Ground (-) to operate. These can be
found at multiple points in the vehicle. The optimum attachment for the 12V (+) Constant is at the battery. The Ground (-)
should be located at a Factory Chassis ground point when possible.
STEP 2: ROUTE THE HARNESSES
Starting at the headliner cutout, route the harnesses to the predetermined locations. Be sure to leave about six inches of
cable hanging through the cutout to allow for working room.
.
STEP 3: PROTECT THE HARNESSES
To prevent harness failures, be sure to avoid sharp edges in the vehicle which could cut or damage the harnesses. When
ever possible, tape the harnesses in place to avoid vibration noises and long-term wear, which could result in failure.
STEP 4: CONNECTING THE POWER HARNESS
When connecting the Power Harness, always insure that the connections are made with the proper gauge T-Taps or by
bolting or soldering the wires. Failure to make a proper connection will result in a system failure in the future.

5 Connecting to the domelight wiring in the vehicle
Remove the vehicle dome light, locate the dome light connector and unplug it. Use a digital multimeter, test all the wires in
the dome light connector, to determine which type of dome light circuit is present.

CAUTION!
It is the installer's responsibility to ensure that the safety equipment in the vehicle is NOT
adversely affected by installation of this system. Ensure that the routing of the harnesses
does NOT obstruct side-curtain airbags, SRS or other safety devices.
IMPORTANT!
NEVER connect the ACC (Red) Power Harness wire to a constant 12V (+) power point, this will
cause the systems to remain powered on, after the car is turned off – resulting in premature
battery drain.
IMPORTANT!
Many vehicles have dome light delay timers which keep the lights on after doors are closed, or
shut off the dome light after it has been on for too long. Make sure these timers don't defeat your
testing - occasionally turn the ignition key on and off, and open and close all the doors.
