So i decided to undertake this journey with a great wiring diagram, test light, and some general electronics knowledge. The issue i found is that i cannot determine which wire on the Radio C3 connector tells the display to switch over to camera view.
What i do know:
Pins 3&4 are the actual image from the camera.
The camera is constantly powered on, but something (tipm is my guess from researching) switches the radio to display the feed.
Pin 6, video signal 1, is not the signalling wire.
None of the pins in the C3 connector provide a testable current to switch the display to the camera feed.
_____________________
I could keep aimlessly cutting the wires until i find the one, but my concern is that if none of the wires apply a 12v current to trigger the change, would i eventually fry the unit by applying one (if i found the one that causes the display change).
Any info would be appreciated.

The SPDT switch will be wired in (after cutting the signalling wire) with the lead going to the radio as the common pole, the other end will be on the NC pole for factory reverse signalling, and the NO pole will be a fused Aux Acc 12v wire for on demand camera.
FYI - getting the bezel off is a breeze with the split bench. Happy to disclose if needed.
