The included backup camera requires specific wiring for proper functionality. Connect the red power cable of the camera to the positive back battery supply and the black cable to the negative battery supply. The yellow video input port of the camera connects to the CAM IN port on the rear of the car radio. Locate the wire labeled "BACK" on the car radio's harness and connect it to the positive power supply (typically the reverse light trigger wire). This ensures the display automatically switches to the reversing image when the car is in reverse gear.
