Towing your vehicle behind your RV is a great way to experience more of the adventure on your cross-country excursions. Whether you're towing a compact car or a full-size truck, CURT has the perfect solution to help you Bring It! CURT towed-vehicle RV harnesses allow you to wire your vehicle for dinghy towing. They plug into your vehicle's wiring system and provide a standard 4-way flat connector to plug into the RV socket and synchronize the vehicle's tail lights, turn signals and brake lights with the RV's. If a custom harness isn't available for your vehicle, this RV dinghy tow wiring harness provides a splice-in option. It has a universal design and comes with butt connectors to splice into the vehicle's electrical system (not compatible with PWM systems). Every CURT towed-vehicle RV harness comes ready to install with all necessary hardware included. They also come with a 4-way flat extension to provide plenty of length to plug into the RV socket, as well as a connector mounting bracket to mount the connector on the vehicle.
