Installation Procedure
1. Identify the polarity of the dome light circuit and set the switch on the bottom of the
overhead monitor housing.
2. Test fit the overhead monitor system on the ceiling of the vehicle, verifying it is not going
to interfere with the safe operation of the vehicle.
3. Once the mounting location of the overhead monitor system has been determined,
carefully mark the location with masking tape.
4. Lower the vehicle’s headliner down to see if a roof support beam is available to screw the
mounting bracket to. If a support beam is not available to screw into, use a ¾” piece of
plywood cut to the appropriate size. Attach the plywood to the roof of the vehicle using
silicone allowing adequate drying time.
5. Screw the mounting bracket in the vehicle. DOUBLE CHECK THE LENGTH OF THE
SCREWS PRIOR TO MOUNTING THE BRACKET.
6. Cut a 1” hole in the headliner along the backside of the mounting bracket for the cables to
pass through.
7. Route cables through the hole to the predetermined location of the AV source(s).
8. Identify the dome light wires in the vehicle and connect them to the corresponding dome
light wires on the overhead monitor system.
9. Plug in the AV cables and power harness into the overhead monitor system.
10. Carefully hold the overhead monitor system to the mounting bracket aligning the
mounting holes while screwing in the screws. (Make sure the wires and cables are not in the
way while mounting the monitor).
11. Connect the Red wire of the power harness to the Accessory wire in the ignition
harness.
12. Ground the Black wire of the power harness to a clean ground spot.
Note: Make sure you keep the ground wire of the model and video source as short as
possible to prevent any type of unwanted vehicle noise.
