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 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.
