You want to connect the camera to your positive reverse light wire so that it is ONLY on when you are in reverse. You will then parallel + or - trigger to your radio. It should have a wire for reverse input. Mine is a pioneer and they let you do either a positive or negative trigger. I set it to positive and just paralleled another wire from my reverse lights where the camera's positive lead connected on the tail light harness.
