Wiring a trailer usually means tapping into factory wires, but this harness skips all that. The Curt T-Connector plugs directly into existing tail light connectors to create a 4-pole flat trailer plug. No splicing or guessing which wire does what—just click it in place and it’s ready to use.
The built-in powered converter keeps the vehicle’s electrical system isolated from the trailer wiring. That means no overloading the factory circuits when you hook up trailer lights. It delivers steady, clean power for running lights, turn signals, and brake lights every time you tow.
This harness routes through existing factory grommets and trim, so the wiring stays protected and out of sight. No drilling or exposed sections hanging under the bumper. The result is a neat, factory-style install that looks like it came that way from new.
The 4-pole flat connector provides all the essential light functions—running, turn, and brake signals—so your trailer stays visible and legal on the road. It’s the common setup for small utility trailers, boat trailers, or campers with standard lighting systems.
