Features to know about

Installs Without Cutting or Splicing: Plug-In Harness

Wiring a trailer can be a headache if you have to cut into factory wires. This Curt T-Connector makes it easy with a plug-in design that ties right into existing vehicle connectors. No splicing or guesswork—just plug it in and you’re ready to tow.

Built for Reliable Trailer Lighting: 4-Flat Connector with Powered Converter

The harness comes with a 4-pole flat trailer connector that powers running lights, turn signals, and brake lights. Its powered converter keeps the trailer wiring separate from the vehicle’s electrical system, protecting sensitive electronics and ensuring consistent lighting every time you hook up.

Ready for DIY Installs: Factory Tow Package Connection

This T-Connector is designed to work with the factory tow package, so everything plugs into place cleanly. It’s a straightforward setup most people can handle on their own without specialized tools or rewiring the vehicle.

Clean, Durable Setup: Plug and Lead Design

With its plug-and-lead layout, the wiring routes neatly along existing paths for a tidy finish. Once connected, the weather-ready 4-flat stays secure and easy to reach whenever you need to tow.
