A Curt custom OE 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 5-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). It comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all Curt connectors are thoroughly tested for optimal functionality.
