Wiring for trailer lights can be a headache if you have to tap into factory wires, but this Curt T-Connector makes it simple. It plugs directly into existing vehicle connectors to create a 4-pole flat trailer connection. No need for splicing or modifying the wiring—just plug it in and it’s ready to work.
The 4-flat connector gives you what you need for standard trailer lighting—running lights, turn signals, and brake lights. It’s the common setup for utility, boat, and small cargo trailers. Once connected, you’ll have the lighting functions needed to tow safely and stay visible.
Designed with a visible plug-and-lead layout, this harness makes installation clear and fast. Each connector fits only one way, so there’s no confusion about where anything goes. It’s built with everyday installers in mind—simple connections that get the job done without extra wiring work.
Some vehicles don’t come with a factory tow package, but this harness doesn’t need one. The direct-fit design uses no converter box, keeping things uncomplicated while still delivering dependable trailer lighting power every time you hook up.

Very easy to install
Fast, easy, and idiot-proof. It's very well made and works perfectly.
Easy install
My trailer hitch and wiring harness for 2005 Chevy Impala fit perfectly. I've never had anything go together as smoothly as this. Excellent service and delivery. It doesn't get any better!
Second time I've ordered hitch and wiring for a car purchase. Both fit perfectly and the tooling to aid assembly of hitch bolts did the trick
