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 CURTs 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 vehicles 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. They come with dust covers to keep your connector clean when not in use.

Whatever the next checkpoint is on your adventure -- whether its getting your bike on the trail before sunrise or making it to the campground before dark -- CURT class 2 hitches let you Bring It with confidence. These receiver hitches are made to handle most light-duty towing applications and offer a custom fit for your vehicle. Typically used on full-size cars, crossovers, compact SUVs, minivans or even compact pickup trucks, a CURT class 2 trailer hitch complements the design of smaller vehicles. This particular class 2 hitch is made to be a custom hitch for certain years of the Buick Regal Sport and Chevy Malibu (to verify vehicle compatibility, see application info). It offers a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. Class 2 trailer hitches can typically be used to tow a variety of lightweight trailers, such as a small utility trailer, small fishing boat trailer or popup camper (NOTE: Never exceed the lowest weight capacity of any towing component). They are also perfect for adding cargo space to your vehicle with a bike rack or cargo carrier. This class 2 hitch features a 1-1/4 in. receiver tube to accept a ball mount shank or other hitch-mounted accessory. For safety, it is tested in accordance with SAE J684. A custom trailer hitch design requires extra care, and as such, CURT class 2 hitches are engineered using real vehicles and hands-on research. We use high-strength steel, robotic welding and rigorous testing to produce hitches that are built to fit your lifestyle. To ensure that each hitch will be a reliable extension of your vehicle, we also finish our hitches in a co-curing of liquid Bonderite and black powder coat, giving them long-lasting rust and wear resistance.

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. Although 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, universal 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 plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Chevy Traverse (factory tow package required; to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. 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.

If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Buick Encore (to verify your vehicle compatibility, see application info).

You have a picture in mind of your next destination -- maybe its the boat landing at your favorite fishing spot, maybe its a campsite that overlooks one of natures masterpieces, or maybe its the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.
