Wiring a trailer can be tricky when you have to cut into factory wires, but this harness skips all that. The Curt T-Connector plugs directly into the vehicle’s existing wiring ports in the rear cargo area. No wire splicing, no confusion—just a quick connection that’s ready for towing lights right away.
Some vehicles have separate turn and brake signals, while most trailers use a combined system. This harness includes a taillight converter that merges those signals automatically, so your trailer lights work exactly as they should for stop, turn, and running lights. It takes the guesswork out of wiring differences.
The connection point hides behind trim near the driver-side jack compartment, keeping the setup neat and protected from damage. Once you find the factory plug taped to the inner wall, just snap in the Curt connector and route the 4-flat end to your hitch area. The harness stays tucked away and out of sight when not in use.
The 4-pole flat connector is ready for small trailers, utility haulers, or light-duty setups that need basic lighting functions. If you ever need more connections later—like adding electric brakes or a charge line—you can pair it with kits such as ETBC6 or ETBC7 for 6- or 7-way wiring without redoing your base harness.
