I know this is a common upgrade but I need a little bit of help. I’m removing the rear camera and I was hoping to see an RCA cable and power cable. Instead there is this weird plug. The old unit is a Clarion CJ-750E monitor. Ultimately, I’m trying to just get key operated 12 V power at the rear camera. Not sure if one of these pins in this plug will do that for me. My guess is that there is a ground, power, and others that carry the video signal. Has anyone had experience with this?
