You don’t have to splice or tap into factory wiring with this harness. The Curt T-Connector plugs straight into the existing tail light connections, giving you a ready 4-pole flat trailer connector for brake lights, taillights, and turn signals. It’s a straightforward, hidden setup that keeps everything neat behind the panels.
The built-in powered converter uses its own 12-volt feed to operate trailer lights without drawing power directly from the vehicle circuits. That direct battery connection prevents overloads and keeps the factory wiring safe, especially when towing trailers with LED lighting or added accessories.
The 4-flat connector handles the basics—running, turn, and brake lights—and can be expanded later if you need a 7-way setup for trailer brakes or 12-volt charging. It’s a solid starting point that pairs easily with add-on kits when you’re ready for more capability.
The included hot lead and fuse holder wire directly to the positive battery terminal to supply clean power to the converter. It’s the one extra step that makes the system reliable long-term. Once connected, you’ve got consistent voltage and lighting every time you tow.

It is doing well after another year 2 total. Have used it for 3 x-country moving trips and several instances of hauling things around town. Electrical and mechanical have worked fine.
