Wiring a trailer doesn’t have to mean chasing wires or guessing at connections. This Curt T-Connector harness plugs straight into the existing tail light wiring to give you a 4-pole flat trailer connector. There’s no cutting, no splicing—just a clean plug-in install that gets your trailer lights working fast.
When you hook up your trailer, this harness delivers reliable power where it counts—up to 3 amps per stop/turn circuit and 5 amps for the taillight circuit. That’s plenty for most standard trailer lighting setups, so your signals stay bright and consistent every time you hit the brakes or turn.
A powered converter keeps your vehicle’s circuits safe by drawing power directly from the battery instead of the light wiring. It isolates the trailer load and prevents feedback that can cause blown fuses or flickering lights. You get dependable trailer lighting without putting extra strain on your car’s electrical system.
The harness uses factory-style connectors that snap right into place, keeping everything tidy and well-fitted behind trim panels. The end result is a clean 4-flat plug ready for running lights, brake lights, and turn signals—so you can tow with confidence knowing everything is wired the right way.
