Adding trailer lights is easy when the wiring just plugs in. This Curt T-Connector harness connects directly to the factory tow package port, giving you a ready-to-use 4-pole flat trailer connector. No splicing or wire chasing—just snap the plugs together and you’ve got running lights, brake lights, and turn signals ready to go.
Trailer wiring can overload vehicle lighting circuits if it isn’t isolated. This harness includes a powered converter and a built-in 10-amp fuse to protect your vehicle’s electrical system. The converter draws power safely through its own circuit while still passing clean signal for each lighting function.
Once your 4-way is in place, you can easily expand your setup for larger trailers. The connector pairs with adapters like the ETBC7 kit to add a full 7-way plug for electric brakes or auxiliary power. It’s a solid foundation for any towing configuration down the road.
The harness routes neatly along the frame rail at the rear—out of sight and protected from road debris. Using the factory ports means fewer exposed wires and a cleaner look behind your hitch. Everything tucks in tight so it's ready for the long haul.
