Wiring a trailer usually means splicing into factory wires, but this harness skips that step. The Curt T-Connector plugs directly into existing tail light connectors to give you a working 4-flat trailer plug. It’s a simple plug-and-play setup with no cutting or soldering needed.
This harness uses a powered converter to draw power directly from the vehicle battery instead of the tail light circuits. That keeps the trailer lights bright and protects sensitive vehicle electronics from overload. If you ever need to troubleshoot, you can easily check voltage at the converter’s input and output to confirm proper function.
When not towing, the 4-flat connector stays tucked inside the trunk. When it’s time to tow, just pull it out and close the hatch over the wire—the gasket flexes to protect it from pinching. Storing it inside keeps dirt, rain, and road debris off the terminals so they don’t corrode or drag on the ground.
The 4-flat trailer connector provides running lights, turn signals, and brake lights—everything needed for small and mid-size trailers. It’s a dependable setup that works seamlessly with your existing hitch so you can hook up and go without extra adapters.

Great!! Easy to use, no fraying when rear door closed. When not in use we tuck in under the back floor access. Not a problem with it.
