A CURT custom wiring 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 CURT’s custom wiring 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 vehicle’s electrical system, to readily accept a custom wiring connector. With a CURT custom wiring connector, there is no need to tap into the taillight assembly because a special socket is already provided. This special custom wiring connector actually provides two connector sockets for a multipurpose option. It plugs into an OEM USCAR connector and offers a 4-way flat and 6-way round connector (see application info to verify fitment with your vehicle). It also comes with a mounting bracket for easy installation. CURT custom wiring connectors are designed to be long-lasting and simple to install.

A CURT front trailer hitch allows you to use the front end of your vehicle for a variety of towing applications. They can be used for mounting a winch, a snow plow, a number of towing accessories and can even be used for some trailering applications. When space is limited, a front trailer hitch is commonly used to hold a cargo carrier, freeing up space inside the vehicle for extra cargo and making the rear mount receiver available to pull a trailer. At the boat ramp, your boat trailer can be hitched up to the front receiver hitch, giving you better control over the trailer as you launch. Some of the other accessories that can be used with a front tow hitch are the CURT winch mount, step pad, license plate holder, spare tire mount, skid shield and tow hooks.

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.

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 or trailer hitch. 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. These CURT extension harnesses are designed to work with 7-way RV blade connectors and come with 7′ of wire. Ten harnesses are included in each package. They are 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.
