CURT Custom Wiring Harnesses Provide a Reliable Connection for Towing a Trailer
A CURT tow wiring harness is the ideal way to ensure a reliable wiring connection when towing a trailer. Whether you're planning a family outing to the lake or need to equip your truck for the jobsite, a CURT hitch wiring harness provides a secure connection without any cutting or splicing required. Every CURT wiring harness is vehicle-specific and comes with all necessary components for a complete installation.
If your vehicle doesn't have a tow wiring harness, we have the vehicle-specific hitch wiring harness you need to outfit your truck for towing. For vehicles already equipped with a trailer wiring connection, CURT offers replacement plugs and sockets, as well as adapters to fit different types of trailer plugs.
CURT also offers custom wiring harnesses. It's helpful to know there are two types of custom wiring — connectors and harnesses. Connectors are designed for vehicles that have an electrical socket located somewhere at the rear, which provides a place to plug in CURT trailer wiring.
Our wiring harnesses are the perfect solution for vehicles without a factory electrical socket. It simply plugs into the vehicle's taillight wiring without requiring any cutting or splicing.
When it comes to connectors and harnesses, the result is the same — a standard trailer wiring connection that provides a reliable connection. A custom wiring harness, however, does use multiple plugs to connect to the vehicle's taillights and is sometimes called a T-connector. This is because this type of tow wiring harness Ts into the vehicle's electrical system using two or more plugs, bridging the existing connection and branching off a new connection for the trailer wiring.
