The camera has two wirescoming out of it, and a heavy (thick) section . Body ground the correct wire, and connect the positive wire to that usually goes to the backup light circuit, to a switch if you want an on off or hook it up to a ignition activated wire so it is on all the time. I've got my TV on the ignition, the rear camera to the back up lights and the front on a switch. DO NOT CUT THE HEAVY SECTION OF THE CAMERA WIRES, AS THIS SECTION IS THE ANTENNA.
