Trailer Wiring Recommendation for Motorhome to Allow Flat Towing Lighting to Connect

Question:

I am towing my car 2 wire system behind my motorhome 3 wire system. What converter should I use to go from 3 wires to 2 wires?

Does your motorhome have trailer wiring installed on it already? If so, you wouldn't need to add anything to it as it would already be converted properly. If not you would need the trailer wiring kit part # 119250KIT that would convert the separate signals to combined. Then to convert it to a 7-way you would need the part # 37185.

For lighting on the tow vehicle you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.
