“A CURT trailer hitch is the key to pursuing your passions, whether you’re taking the family boat out for an afternoon on the water or packing up the mountain bikes for a day on the trails. This CURT class 2 hitch is perfect for towing a small trailer, such as a boat trailer, lightweight camper or utility trailer. It can also be used to mount a hitch cargo carrier or bike rack (never exceed the lowest-rated towing component). Like all CURT custom hitches, this class 2 trailer hitch is made for a vehicle-specific fit. It is engineered to seamlessly integrate with select years of the Chevrolet Equinox and GMC Terrain (see application info to verify fitment). It is rated for 3,500 pounds gross trailer weight and 525 pounds tongue weight. It is also equipped with 1-1/4″” x 1-1/4″” hitch receiver to accept the included ball mount. The ball mount that comes with this hitch kit has a 3/4″” trailer ball hole and can be positioned in the drop or rise orientation for level towing with your specific trailer (trailer ball not included). Like all CURT custom receiver hitches, this class 2 hitch is designed, manufactured, finished and tested with the utmost care. It is engineered for a precise fit, easy installation, maximum towing strength and an integrated look on the vehicle. It is also tested to SAE J684 protocols for safety. This class 2 trailer hitch is finished with our industry-leading dual-coat process for unparalleled rust, chip and UV resistance. It is descaled for a smooth surface, submersed in liquid A-coat for rust prevention inside and out, covered with a highly durable powder coat, and finally co-cured for a dependable shield against the elements. This class 2 hitch comes with a ball mount, hitch pin and mounting hardware for a complete installation.”

$36.99
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 connector and offers a 4-way flat and 7-way RV blade connector. It comes with a mounting bracket for easy installation and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment). 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.

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 vehicle’s 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 Equinox and GMC Terrain (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 you’re 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.

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 connector and offers a 4-way flat and 7-way RV blade connector. It comes with a mounting bracket for easy installation and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment). 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.

Stress is the last thing you should feel when towing a trailer — whether you’re 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 vehicle’s 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 4-way flat socket while retaining use of the existing OEM socket. It is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle).
