CURT 52107 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 vehicle-specific application, using OEM-compatible plugs to “T” into the vehicle’s wiring without any need for cutting or splicing. This particular RV dinghy tow wiring harness is designed for select years of the Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD.
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 are able to operate in conjunction with your RV’s lights, signaling other drivers and functioning just like a standard trailer in tow.
The simple plug-and-play design of CURT towed-vehicle RV harnesses makes installation a breeze, but these custom harnesses are also built for lasting durability. Each harness features integrated block diodes. These diodes isolate the vehicle’s electronics from the RV signals in a way that protects them from overheating and short circuiting.
Each CURT towed-vehicle RV harness comes 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.
