Will be installing this thing soon, but the installation instruction are a bit to be desired. There are read wire leads coming off each end of the long video cable that connects to the head unit camera input/ camera output. I assume that the red wire should be grounded. Is that correct? Looking forward to seeing how the radar functions.
Hi Canman,
I would check to be sure the red wire is connected to ground of the video cable with a multimeter(looks like it might be). This would be better than the way I back up, listening for the crunch.
Thanks. I think I understand now. The red wire is intended to connect the back-up/ reverse light (+12 VDC) at the rear of the vehicle to the reverse input wire on the monitor/ head unit. This way you do not have to run a separate wire from the rear to the front. I intend to have the option to see in reverse other than when I'm actually in reverse primarily to see when I am towing something. After watching a few YouTube vids, I realized to accomplish that some diodes are needed to prevent the reverse lights from coming on when triggering +12VDC with a manual switch.
