CURT custom wiring allows you to outfit your vehicle with a standard connector for plugging in trailer wiring. Each T-connector is vehicle-specific and plugs into existing wiring without any splicing required. Our custom wiring is also thoroughly tested for reliability.
Of the two types of custom wiring, connectors use a single plug while harnesses use multiple plugs. The result is the same: a standard trailer wiring connection, usually in the form of a 4-way flat. Neither option requires splicing.
However, because a custom wiring harness uses multiple plugs to connect to the vehicle's taillights, it is sometimes referred as a T-connector. It 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.
