"The camera has a four pin plug. One of those wires controls the backup monitor. That’s the wire that needs to be connected to the reverse lights."

Any possibility you could post the schematics if any were included? I deal with analog cameras quite a bit at work, typically they need 2 wires for power, 2 wires for the video signal, so I'm wondering how there is a signal wire to fire the monitor for the camera in cab.
