I have just purchased a Reese P.O.D. (Power On Demand) #83502 brake controller. It has four wires (Black - labeled battery +, Red - labeled stoplight, White - labeled ground -, Blue - labeled brake).

I have the factory tow package on my 05 XL. With it came the wiring harness and relay. The factory harness has 5 wires and are labeled Brown - illumination feed, green - stop lamp, red - feed wire from battery, blue - to trailer electric brakes, white - ground circuit.

How the hell do I wire this thing? Thanks in advance for any help you may offer.

 

Reese ------------- OEM

Black wire --------- Red wire
Red wire --------- Green wire
Blue wire ---------- Blue wire
White wire --------- White wire

Cap off the Black Illumination wire on the oem pig tail. You shouldn't need it. I didn't need it. My controller is a digital controller made by Hidden Hitch, it also only had the same 4 wires.

 

Thank you very much. I am an idiot when it comes to wiring stuff like this and understanding their directions.
