  • Stress is the last thing you should feel when towing a trailer -- whether youre hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it. CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Though this special socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicles wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular connector provides a 5-way flat socket while retaining use of the existing OEM 7-way. It is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle). It comes with a dust cover to keep the connector socket clean when not in use.

  • 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 in a length of 10. It is compatible with certain models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram and Toyota (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.

  • The CURT OEM puck system 5th wheel adapter for Chevy, Ford and GMC pickups combines the functionality of CURT 5th wheel puck system products with the strength and convenience of the truck bed puck system. The adapter provides a set of industry-standard 5th wheel rails to securely mount a CURT 5th wheel hitch or roller into the bed of your truck. It is designed to fit select model years of the Chevrolet Silverado, GMC Sierra 2500 HD and 3500 HD and Ford F-250 and F-350 Super Duty (see application info to verify fitment). It features a set of adjustable, quarter-turn anchors to quickly and easily drop into the pucks and provide a moveable platform for the 5th wheel coupling point. This puck system adapter requires a specific puck system for installation (year range specific). It features a capacity of 25,000 lbs. and is compatible with all CURT 5th wheel legs and rollers (weight capacities are limited to the lowest-rated towing component). Like our other OEM puck system 5th wheel products, the key feature of the 5th wheel puck system adapter is its quarter-turn anchors. With the hitch initially bolted onto the adapter, the adapter can easily be dropped into place whenever needed and secured with the quarter-turn anchors. The anchors can also be adjusted to help eliminate chucking noises between the adapter and under-bed platform while towing. When you are finished towing, simply turn the anchors to remove the entire assembly within seconds. The CURT 5th wheel adapter for select Chevrolet, Ford and GMC pickup trucks provides the ultimate in versatility for the CURT 5th wheel line. It tested for safety in accordance with SAE J2638 and is coated in a highly durable carbide black powder coat finish to protect against scratches and rust.
