Thread: Help needed to wire older Polaris cm 35 reversing camera

HI. Just bought a reversing camera off ebay. It's a wire in jobby, not a wireless. Supposedly a quality one, had been factory fitted to a Landcruiser by Toyota. Don't know why they would have had it removed but anyway. I know all the buyer beware stuff but this cost me $50 so I got nothing to lose..

Anyhooooo, it has the Monitor at one end, and at the other end of course the little camera. Has the harness and a socket for each at either end. There is a red and black wire down the back of the harness where the camera plugs in, and a single red wire at the monitor end? I thought it was strange the power leads were at the rear end but on reflection probably easier to find a pos and neg at that rear of the vehicle than muck around in the dash. The single red wire at the monitor end has me stumped though? Has anyone had any experience with these?

Its an older b&W Polaris CM 35 by the way. Apparently the power cable is at the rear to connect to the reversing light. Still don't know what the extra red wire at the front is for though. I hooked it up to my car charger and the screen lit up but couldn't get any functions etc
