Hi you love Ehm I try to explain it uncomplicated. How exactly do I connect the camera to ? Have thought so Camera has a minus and plus pole (requires 12v) The video cable has this yellow chinch connection as well as a red cable (beid side) The car radio has a reservation cable in the wire harness which detects if e.g. the backward gear is inserted. (There as I understand are also 12 v voltage.) Now camera rear mount mass look for point .. the red cables both twist together and turn together d at the front connect the other end of the red cable to the lapel. Will my bill open or will it run into the void ? Below is a picture fals it is helpful Thank you
