Adding trailer lights doesn’t have to mean stripping and splicing wires. This Curt T-Connector plugs straight into the existing wiring, giving you a 4-flat trailer connector without altering any factory circuits. Just snap it into the matching plug behind the trim panel, and you’re ready for towing lights that work right out of the box.
The built-in powered converter keeps your trailer lighting separate from your vehicle’s circuits. It uses a dedicated “Battery +” wire to power the trailer lights directly from the vehicle’s battery instead of loading down the taillight wiring. That means steady, reliable light signals and less risk of blowing a fuse when you hook up your trailer.
The 4-flat connector delivers all the essentials—running lights, brake lights, and turn signals—so it works with most small utility, boat, or rental trailers. It’s also easy to adapt later if you add a brake controller or upgrade to a 7-way setup.
The converter box mounts neatly inside the cargo area using double-sided tape, keeping it protected from water and road grime. When not in use, you can roll up the 4-flat and store it out of sight, then pull it out through a grommet or rear hatch whenever you need it.

I still have the 2003 Jeep Grand Cherokee that they were installed on and all is doing well. I am a Scout leader and hunter and pull a Scout trailer on trips and have a large flat trailer I pull on hunting and fishing trips. It went on very easy.
