When wiring your backup camera, you can splice the camera power into the reverse light signal or you can splice into the running light circuit to give you an observation camera that gives you the view at any time.

To determine which of your wires is the positive power wire, you will need to use a circuit tester like # PTW2992. If wiring your reverse light circuit you will need to shift into reverse and then check for power using the circuit tester. If wiring through your running/parking lights, you can turn on the lights and use the circuit tester to determine which wire is power.
