  • A CURT custom original equipment vehicle-to-trailer connector (sometimes called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURTs OE vehicle-to-trailer connectors come into play. A custom wiring connector uses a single original equipment plug to plug into a special socket provided by your vehicle. Though this option is not available on every vehicle, some automotive manufacturers design their vehicles to be easily equipped for towing by supplying a socket, integrated into the vehicles electrical system, to readily accept a custom wiring connector. With a CURT custom OE connector, there is no need to tap into the taillight assembly because a special socket is already provided. This special custom vehicle-to-trailer wiring connector provides a multi-function connector socket. It is designed to plug into a circular 7-prong OEM socket and replace a factory-equipped 7-way connector with a 7-way RV blade and 4-way flat. It specifically offers a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle).This multipurpose socket comes with its own backup alarm, a mounting bracket and all necessary mounting hardware for a complete installation. CURT custom vehicle-to-trailer wiring connectors are designed to be long-lasting and simple to install. They come with dust covers to keep your connector clean when not in use.

  • There is nothing like the luxury and power that go along with heavy-duty towing. 5th wheel RVs 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, 5th 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 5th wheel / 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 5th wheel or gooseneck trailer. This CURT extension harness is designed to work with 7-way RV blade connectors and comes with a cover for a seamless installation in the truck bed. It is compatible with a certain models of Chevrolet and GMC trucks (see application to verify fitment). 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.
