T-Connectors

A CURT custom vehicle-to-trailer wiring harness (also 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 vehicle-to-trailer wiring harnesses come into play. Custom wiring harnesses plug into your vehicle’s electrical system using original equipment (OEM) connectors.

Leading the industry in towing electrical products, CURT offers two options for custom vehicle-to-trailer wiring. Our custom wiring harnesses use two or more OEM connectors to plug into your vehicle’s electrical system, typically at the tail light housing. The harness provides an additional connector in the form of a 4-way or 5-way socket that branches off to allow the trailer to be plugged into the vehicle’s power system. The other custom wiring option is our custom wiring connectors. These use a single original equipment connector to plug into a specific socket provided by the vehicle. Automotive manufacturers design some 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.

CURT custom wiring harnesses range in complexity, with some using a converter and others consisting only of wires and plugs. In concept, however, all custom wiring harnesses follow the same format. When laid out, the basic structure forms a T-shape, and for this reason, they are frequently referred to as T-connectors.

CURT custom vehicle-to-trailer wiring harnesses and connectors are designed to be long-lasting and easy to install. Our wiring harnesses with converters utilize our advanced surface mount technology (SMT) circuits with circuit protection to ensure consistent power for your trailer. The SMT components perform better than the older through-hole-mounted circuits and generate less heat. The vast majority of our electrical converters are made in the USA, so you can tow with peace of mind, knowing you have a reliable electrical solution.
