Wiring a trailer usually means finding and tapping factory wires, but this harness avoids all that. The Curt T-Connector plugs directly into the vehicle’s existing wiring to create a 4-flat trailer connector. There’s no cutting, no splicing—just plug it in and it’s ready for use.
The harness uses a hidden, plug-and-lead layout that keeps the connections tucked out of sight for a clean finish. It ties neatly into the vehicle end connector so nothing hangs loose or looks out of place once installed.
A built-in powered converter isolates the trailer wiring from the vehicle’s electrical system. That helps protect sensitive components and ensures that running lights, turn signals, and brake lights on the trailer work correctly every time.
The included 4-flat connector covers the essentials—running lights, turn signals, and brake lights—so you can tow small or midsize trailers safely. It’s the standard connection most light-duty trailers use and pairs easily with standard adapters when needed.

Its pretty rare that the failure of a taillight converter would cause just one function to fail. Its more likely that none of the taillight functions would work. You can confirm if the converter is faulty be either trying a different trailer on the vehicle or by trying the trailer on a different vehicle. You could also use a circuit tester like # PTW2993 on the pin fed by the yellow wire while the left turn signal is activated.

Im just an old bodyman 76Now but I have used the Curt Trailer Hitches and wiring set ups on several of Mine and Customer rigs. They Fit perfectly and bolt right up and the wiring is so easy to install without butchering the original wiring of the car or truck I am working on. They are a really nice set-up! I Wish those you have never tried other trailer hitches and Wiring set ups could Know what a difference it makes in Time, Stress, and Ease to use the Curt Trailer Hitches and wiring set ups. Thanks for letting me comment on your products! Warren, Just an old bodyman with 56 years of beating on cars in Montana.
