Wiring a trailer can be tricky if you have to cut into factory wires, but this harness keeps it easy. The Curt T-Connector plugs right into the factory tow package connection and gives you a 4-way flat trailer connector. It’s built as a direct fit, so there’s no wire tracing or splicing needed—just plug it in and you’re ready to roll.

With the 4-pole flat connector, your trailer’s running lights, brake lights, and turn signals come on exactly when they’re supposed to. It provides a clean, consistent signal every time you tow, so your trailer lighting stays in sync with your vehicle.
This harness uses factory-style connectors that match perfectly with the vehicle-side plug. The design lines up male and female pins the way they should, taking out any guesswork. You can see right away that it’s made to fit—the plugs lock together securely for a solid connection.
No need to figure things out from scratch—this kit has clear install directions and matching video guides that walk through the full process. You’ll know exactly where each connection goes before you even start, making it a quick afternoon project instead of a weekend one.

How do I know if my 2008 is tow ready for the intalation of this particular kit? I only ask this from the last comment response to the 2010 instalation. Thanks!

Harness still works just fine and I haven’t had any issues. It’s stored inside the car when not used so that’s helpful.
