I hate to admit this. I wired up the reverse camera and forgot to wire the power to the plate light. It will be a pain to take it all loose in the hatch area. Those that have done this knows. Where can I tap in to get power for this light? The old plate light harness is still there and has a brown and white (maybe grey) wires coming from it. Can I just tap into that? If so which is power and ground because the camera plate light has a red and black wire. Thanks.
