I have a 2017 chevy 2500 with a locking tailgate and therefore have an 8 pin backup camera harness. The backup camera has 6 wires and I'm trying to wire in a 4 pin/wire backup camera that is on a truck camper I purchased. I'm trying to find the pin/wire definition on the OEM backup camera so I know how to wire in the new 4 pin. I figured out which two wires are for the locking tailgate, but need the x6 for the camera. camera wire colors = red, yellow, white, black, black, brown. If anyone has this definition it would be greatly appreciated.
