Wiring a trailer can be a hassle, but this Curt T-Connector makes it simple. The harness plugs right into your vehicle’s existing factory tow plug, so there’s no need to splice or tap into the tail light wiring. It’s a clean, straightforward install that gets you ready for towing lights in minutes.
When you tow on public roads, working lights aren’t optional—they’re required. This harness gives you a 4-way flat connector that powers your trailer’s running lights, turn signals, and brake lights. It provides everything needed to keep your trailer legal and visible every time you hook up.
Even if your vehicle didn’t come with the full tow package, the factory tow connector is still there and ready to use. This harness connects directly to that plug to activate trailer light functions once the proper fuses and relays are installed. It’s a simple way to get working trailer lights without chasing down wiring diagrams.
The 4-way end includes a dust cap for protection when not in use and fits neatly into standard flat-mount brackets like Tow Ready’s #18144. That keeps the connector handy next to the hitch and out of the way when you’re not towing. It’s a tidy finish that looks like it came straight from the factory.

The connector worked fine once I got the factory plug pushed in all the way, pretty awkward place to connect inside the rear fender on my 2013 Traverse.
