Wiring a trailer can be tricky, but this Curt T-Connector makes it simple. It plugs directly into your vehicle’s existing wiring, giving you a 4-flat connector without having to cut or splice anything. The plug-in design keeps the install clean and straightforward so you can get your trailer lights working fast.
This harness includes a powered converter that isolates the trailer wiring from the vehicle’s sensitive electrical system. That means your running, brake, and turn signal lights work properly without overloading factory circuits or triggering dash errors. It’s built for vehicles without a tow package and keeps everything running safely and reliably.
The integrated 4-pole flat connector gives you what most trailers need—running lights, brake lights, and turn signals. It’s the standard setup for small and midsize trailers, perfect for towing boats, campers, or utility trailers with confidence that everything will light up as it should.
Because it connects at the factory tail light points and routes through existing grommets, this harness gives a tidy install with no loose wires hanging out. The end result looks like it came straight from the factory, with a weather-tight fit that stands up to everyday use.

Product was easy to install and I am happy to report I have not had one issue with the harness or the hitch. Works the way it should work without any issue.
