Wiring a trailer often means tracking down the right wires and hoping you don’t cut the wrong one. This Curt T-Connector skips all that. It plugs inline with your vehicle’s tail light connectors, giving you a clean 4-flat trailer plug without splicing or tapping into factory wiring. The connectors use locking tabs for a secure fit, so once they’re clicked in, they stay put.
The harness tees into the existing wiring and keeps your vehicle lights working exactly as before. It only uses the brake, turn, and running light circuits to power the trailer lights, leaving other systems untouched. You get a reliable trailer connection without interfering with wipers, interior lights, or any other electrical features.
This harness includes a built-in converter that manages the power for your trailer lamps. It’s rated for 3 amps per circuit for stop and turn lights and 7.5 amps total for running lights. That’s enough capacity for most small to mid-size trailers, giving you steady, consistent lighting on every trip.
Good grounding makes all the difference in trailer lighting. The Curt harness grounds directly to a clean metal surface to keep signals strong and predictable. When used with corrosion-free connectors on the trailer side, it helps prevent flickering lights or power drops that can happen with poor connections.
The 4-way flat plug provides standard lighting functions—running lights, turn signals, and brake lights—for safe towing day or night. It’s the common connector style for most light-duty trailers, so you can hook up and go without extra adapters or rewiring.

Great, once I figured out that my vehicle would not power standard lights. Switched to LED and everything worked out fine.
