The reverse light wire is White/Red. This is available on 34 pin connector C322 located along the frame on the drivers side near the front edge of the drivers door, and just happens to be pin #34. It is also available at the TIPM on Black Connector C6 (might be marked 'F') Pin 5. There is a splice point (S120) between the TIPM and C322. The splice is located behind the drivers kick panel, about 6" from the floor.
