Wiring Harness to Flat Tow a 2014 Mini Cooper


I want to buy the RM-154 and wire my Mini Cooper. This will allow me to tow it using a tow dolly. What I cannot find is what wires on the mini cooper I need to use. There are 5 wires going into the light: green/blue brown black/yellow blue white and light blue. Can you tell me which will connect to the RM-154 wires. Thanks

The Roadmaster Universal Hy-Power Diode Wiring Kit, part # RM-154 will work great for flat-towing your Cooper.

Since you have a 3-wire(separate) system, the brake light and turn signals are sent along different wires. You can use a circuit tester like part # 40376 to test your wiring. Have someone sit in the driver seat and run through the functions while you test the wires at the back of the tail lights.

I have attached a drawing that shows the wiring diagram for installing this system. You will want to know what the wiring is on your motorhome and follow the diagram.
