Wiring a trailer doesn’t need to mean cutting into factory wires. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs straight into existing tail light connectors. It’s a true plug-and-play setup that gives you trailer lighting without the mess of splicing or chasing wires.
Once connected, the wiring stays tucked out of sight for a clean appearance. The hidden plug and lead layout uses existing trim paths and grommets, so nothing hangs loose or looks out of place. It blends in like factory equipment while staying protected from dirt and weather.
The built-in powered converter safeguards sensitive vehicle wiring while delivering steady power to trailer lights. It keeps the circuits isolated, which helps prevent overloads or feedback that can trigger vehicle warning systems. Everything lights up bright and consistent every time you tow.
The 4-flat connector provides the basic lighting functions—running lights, turn signals, and brake lights—used on most small and mid-size trailers. It’s the standard plug you’ll find on boat trailers, utility trailers, and campers, so you can hook up and go right away.

Very easy install. The hardest part without a lift is running the power lead to the battery. That is because you are on your back under the car but if you have access to a lift that is simple too. Great product.
I have bought a hitch & wiring from etrailer for every vehicle I've owned for the last 15 years. 3 cars & 2 SUVs later I still highly recommend them. Easy instructions to follow and spot on parts fitment. I will continue to buy from them in the future no questions asked.
