Wiring a trailer doesn’t have to mean splicing factory wires. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs directly into existing tail light connections. It’s a clean, hidden install that keeps factory wiring intact and ready to tow without extra work.
This harness gives you a standard 4-flat connector that powers running lights, turn signals, and brake lights on your trailer. It’s the basic setup most small utility, boat, or camper trailers need to tow safely and legally.
Designed as a plug-and-lead system, the harness comes ready to install without special tools. Just match the connectors and route the lead where you want it. Most folks can have it wired and tested in a short afternoon.
Vehicles without a factory tow package can still handle towing needs with this harness. Built with an integrated converter, it safely transfers power from the vehicle’s lighting system to the trailer without overloading circuits. It’s a dependable way to add towing capability when your setup doesn’t already include it.
