Trailer wiring doesn’t have to mean chasing wires or hard-splicing connections. The Curt T-Connector plugs directly into the factory port, giving you a clean 4-way flat trailer connector without touching the vehicle’s original wiring. It’s a true plug-and-play setup that keeps things neat and avoids mistakes.
This harness uses a powered converter that draws power directly from the battery instead of back-feeding through the vehicle lights. That isolates the trailer load so your vehicle circuits stay safe from overloads or shorts. It’s a reliable setup for running trailer lights the right way.
Everything tucks neatly behind the trim panels using existing factory grommets and openings, so there’s no visible mess or dangling wires. You just pull back the panel, plug in, mount the converter box with the included tape, and reinstall the trim. Most installs only need a 20-amp fuse in the designated fuse box slot to activate the tow circuit.
Once installed, you’ve got a standard 4-flat connector ready to power your trailer’s running lights, turn signals, and brake lights. It’s the common connection used on most small and mid-size trailers, giving you everything you need to tow safely and stay road-legal.

After a year of use pulling a small trailer and a bike hitch the Curt trailer hitch looks brand new and working as advertized. Funny you should send this follow-up earlier, this week I just recommended Etrailer and a Curt hitch to my grandson!
