4. Lower the vehicle’s headliner down to see if a roof support beam is available to screw the
mounting bracket onto. 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 OHM102/OHM153 and video source as short
as possible to prevent any type of unwanted vehicle noise.
