CURT Custom Towed-Vehicle RV Wiring Harnesses

CURT towed-vehicle RV harnesses are the ideal solution to connecting your vehicle's electrical system to your RV while dinghy towing. Each RV harness is made for a vehicle-specific application, using OEM-compatible plugs to "T" into the vehicle's wiring without any need for cutting or splicing. With a towed-vehicle RV harness installed, hitching up your vehicle behind your RV is fast and easy. Simply plug the provided 4-way flat connector from the front of the vehicle into the RV's 4-way flat socket. The RV harness uses the vehicle's existing taillights, turn signals, and brake lights, eliminating the need to purchase additional lighting. The vehicle's lights can operate in conjunction with your RV's lights, signaling other drivers and functioning just like a standard trailer in tow. Along with their plug-and-play design, these custom harnesses are also built for lasting durability. Each harness features integrated block diodes that isolate the vehicle's electronics from the RV signals in a way that protects them from overheating and short circuiting. CURT towed-vehicle RV harnesses come with a 4-way flat extension to reach the RV connector socket, a mounting bracket to help keep the wires ordered and protected on your vehicle, and all the necessary hardware for a complete installation.
