Wiring a trailer doesn’t have to mean splicing or chasing down factory wires. The Curt T-Connector plugs directly into your vehicle’s existing harness behind the rear bumper to create a clean 4-flat trailer connector. It’s a straightforward plug-and-play setup that gets you towing lights in minutes without any guesswork.
Once installed, the 4-flat connector gives you what most trailers need—running lights, brake lights, and turn signals. It’s the standard plug used for small and midsize trailers, and it connects easily to most wiring adapters and accessories.
Starting with a solid 4-way makes it simple to upgrade later. If you decide to add trailer brakes or a 12V charge line, just plug in a 4-to-7 adapter like part #37185 or use an install kit such as #ETBC7. The C56031 provides the base connection needed for either setup, so you can build on it when your towing needs grow.
If you’re adding an LED tailgate light bar or other rear lighting, this harness gives you an easy power source without cutting into the factory wiring. The 4-flat plug provides clean, reliable signal connections that keep your setup looking tidy and professional.
