Curt custom towed-vehicle rv wiring harness, select ram 2500, 3500 - 52114

The Curt Custom Towed-Vehicle RV Wiring Harness is an essential flat-towing electrical solution engineered specifically for select Ram 2500 and Ram 3500 heavy-duty trucks. Designed for motorhome owners and overlanders dinghy-towing their Ram truck, this custom harness connects your towed vehicle’s tail lights, brake lights, and turn signals directly to your RV’s electrical system, eliminating the need for temporary magnetic towing lights.

Built with high-efficiency integrated diodes, this RV wiring kit isolates your Ram truck’s sensitive factory electronics from the motorhome's power supply, preventing feedback, voltage spikes, and costly electrical damage. The vehicle-specific T-connector plugs directly into your truck's factory wiring loom for a clean, plug-and-play installation without wire cutting or splicing. Terminating in a standard 4-way flat socket with a protective rubber dust cover, the Curt towed-vehicle wiring harness ensures seamless, road-legal lighting alignment on every cross-country RV journey.
