Wiring a trailer can be tricky if you have to cut into factory wires, but this harness skips all that. The Curt T-Connector plugs in behind the tail lights for a true plug-and-play install. No splicing or guessing at wire colors—just connect the factory plugs and you’re ready to power your trailer lights.
This harness uses a powered converter that pulls power straight from the vehicle’s battery instead of the tail light circuits. That keeps the factory wiring safe if the trailer ever shorts out or draws too much power. The converter isolates the trailer load so your vehicle’s fuses and electronics stay protected.
The 4-flat connector supplies stop, turn, and running light signals that work perfectly with trailers using LED taillights. The Curt T-Connector # C59DR is built to handle up to 5 amps per stop/turn circuit and 7.5 amps for running lights, so it runs standard or LED lighting reliably trip after trip.
Rather than trying to tap into auxiliary or in-bed power ports, this kit includes a dedicated power wire designed to run to the battery. That direct connection gives the converter a steady 12-volt supply for proper operation and ensures you won’t overload any factory accessory circuits. It’s a bit of routing work up front but gives long-term peace of mind knowing it’s done right.
Once installed, the 4-pole flat connector gives you everything needed for basic trailer lighting—running, brake, and turn signals. It’s the common setup for small utility trailers, cargo haulers, and boat trailers, making this harness a simple and dependable way to get your lights working every time you hitch up.

A year later, and no issues with the wiring harness after about 10k towing and another 10k driving
