Wiring up for towing doesn’t have to mean cutting into factory wires. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs directly into your vehicle’s existing wiring. It’s a hidden, plug-in style harness that keeps the install neat and straightforward, giving you a clean connection ready for trailer lights.
This harness includes a powered converter that draws power straight from the vehicle battery instead of the lighting circuit. That protects sensitive factory wiring and ensures reliable power for your trailer lights. The hot lead must be connected directly to the battery—never to an accessory outlet—to keep your electrical system safe and performing as it should.
Once installed, the 4-flat connector gives you running lights, turn signals, and brake lights—everything needed for most small and mid-size trailers. It’s the same standard 4-way connection used on rental trailers, so it’s ready to hook up when you are.
The power wire can be routed outside and under the vehicle through an existing grommet at the rear. Running it along the frame keeps it protected from heat and moving parts. It’s a tidy way to route wiring without drilling into panels or leaving wires exposed.
