      Description

      Stay Street Legal. This Custom Towed-Vehicle RV Wiring Harness is the ideal solution for connecting your Sierra's electrical system to your RV while dinghy towing. The RV harness uses your Sierra's existing tail lights, turn signals and brake lights, eliminating the need to purchase additional lighting.

      Quality Construction. This Custom Towed-Vehicle RV Wiring Harness is built for lasting durability. The Harness features integrated block diodes. These diodes isolate your Sierra's electronics from the RV signals in a way that protects them from overheating and short circuiting.

      Plug and Play.

Simply plug the provided 4-way flat connector from the front of your Sierra into the RV's 4-way flat socket.

      Application. This Custom Towed-Vehicle RV Wiring Harness is designed to fit 2016-2018 GMC Sierra 1500 models. Includes harness, 4-flat extension, mounting bracket and hardware.
