CURT 52112 is a custom towed-vehicle RV wiring harness for 2025-2026 Ram 1500.
It is for dinghy towing the vehicle behind an RV. The harness uses OEM-compatible plugs to tee into the vehicle's wiring with no cutting or splicing, and its 4-way flat connector at the front of the vehicle plugs into the RV's 4-way flat socket. The vehicle's own tail lights, brake lights and turn signals then work with the RV's lights. Integrated block diodes isolate the vehicle's electronics from the RV signals. A 4-way flat extension, a mounting bracket and the installation hardware are included.
