At this point since there is mention of frying electronics I'm inclined to not do this and just mark it up as lesson learned.

Correct. Powers1 is giving you good info. Pins 85+87 connect to reverse-light-ground (brown) and cam ground. I just crimped two wires together for this and connected them to the 2 grounds. Pin 86 connects to reverse-light positive (yellow/white) and cam positive.

Here's more that may help cam install 1 cam install 2

You can do it
