Hi Gary,

The wiring for the interconnected units is complex but the Bordmonitor receives its permanent 12v battery supply on pin 7 of C0816 (purple/pink wire) and its ignition key switched supply to pin 11 (light green/white wire). Pin 2 (black) on the same connector is earth.

Your connection to the red wire on C0815 applied 12v DC to the RGB red signal input. Unfortunately this may have caused some damage.
