There is nothing like the luxury and power that go along with heavy-duty towing. Fifth wheel RV's offer a deluxe, home away from home experience unlike any other, while gooseneck trailers possess a strength that far surpasses most other trailer options. As with any trailer, however, fifth wheels and goosenecks must be equipped with the proper lighting and electrical systems and tend to require even more complex connectors than a standard receiver type trailer setup. Make things simple with a Curt fifth wheel or gooseneck extension harness. These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your fifth wheel or gooseneck trailer. This Curt extension harness is designed to work with seven way RV blade connectors and comes in a length of 7 ft. When you need a towing electrical solution that allows you to switch back and forth between your receiver hitch and specialized trailer hitch, Curt gets you plugged in.
