Adding trailer lights doesn’t have to be complicated. The Curt T-Connector plugs right into the factory tow package port to give you a clean 4-flat connector for your trailer. There’s no need to cut or splice wires since the factory plug is already in place—just connect it and you’re set.
This harness gives you everything you need to power your trailer’s running lights, turn signals, and brake lights through a standard 4-pole flat connector. It’s the base wiring you’ll use whether you’re towing a small utility trailer or setting up for a future 7-way upgrade.
When you’re ready to add electric brakes or charge a trailer battery, this harness makes it easy to expand. Plug it into an adapter like the ETBC7 or 37185 to step up from a 4-pole to a full 7-way connection without starting over or re-wiring your vehicle.
If your old 4-way connector is damaged or intermittent, this T-Connector restores full lighting function fast. The weather-sealed plug connects directly to the existing tow package wiring to bring back solid signals at the trailer plug with no guesswork about wire colors or routing.
