Wiring a trailer can look complicated, but this Curt T-Connector makes it simple. It plugs right into your vehicle’s existing tail light connectors, so there’s no splicing or guessing. Everything snaps together cleanly behind the trim panels for a fast, factory-style setup that gets your trailer lights running right away.
A built-in powered converter keeps your vehicle’s wiring safe by drawing power directly from the battery instead of the tail light circuit. This isolates the factory system and prevents overload or feedback when the trailer lights are on. It’s the right setup for consistent performance and long-term reliability.
The 4-flat plug gives you all the basics—running, turn, and brake lights—and works with both LED and incandescent trailer lighting. It’s the most common connector type, ready to hook up to most small trailers right out of the box.
Once installed, the 4-way connector tucks neatly into the rear cargo area when not in use. That keeps it protected from weather and road grime, so it’s always clean and ready for your next trip. Pull it out when you need to tow, close it back inside when you’re done—simple and tidy.

I am sorry to hear that, Thomas! What is going on with the harness that you can't use it?
