Wiring a trailer doesn’t have to mean cutting factory wires. This Curt T-Connector harness plugs right into the existing tail light connections for a clean install. No splicing or wire tracing—just connect the plugs and you’ve got a 4-flat trailer connector ready to go.
This harness includes a powered converter that draws power directly from the vehicle battery. That means your trailer lights get the voltage they need without overloading the vehicle’s lighting circuits. It’s a solid setup for consistent performance every time you tow.
Everything hooks up at the rear of the vehicle using factory wiring access points. The design keeps the install neat and contained, so there’s no need to run wires all over or drill new holes. You’ll have working trailer lights in less time and with less hassle.
Once installed, the 4-flat connector gives you all the basics—running lights, turn signals, and brake lights—for small and mid-size trailers. It’s the most common connection out there and works with a wide range of trailer types and accessories.
