Identify the polarity of the dome light circuit and set the switch on the cable connection side
of the overhead monitor housing to match the vehicle’s door trigger polarity. Factory default posi-

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 and is physically safe for the driver and passenger(s).
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 before proceeding.
