Wiring a trailer usually means tracking down wire colors and splicing into the factory harness, but this plug-in Curt T-Connector makes it simple. It connects directly to the vehicle’s existing tail light plugs to give you a 4-pole flat trailer connector with no cutting, no guesswork, and no need for extra parts.

This harness includes a powered converter that isolates the trailer load from the vehicle’s sensitive wiring. It draws power directly from the battery instead of pulling it through the tail light circuits, reducing strain on the system and protecting delicate electronics from overload or feedback.
The harness tucks neatly out of sight with a hidden, factory-style connection that keeps things looking original. The 4-flat lead gives you running lights, turn signals, and brake lights in one compact plug that’s ready to connect to most small or mid-size trailers.
Even if your vehicle didn’t come with a tow package, this kit gives you everything needed on the vehicle end. It’s a full trailer wiring solution that creates a reliable link between the vehicle and trailer for safe, consistent lighting every time you tow.

Product failed in Dec. 2023left blinker started showing up to the car as burnt out, but replacing the bulb didnt fix it. Removing the passthrough connection from the vehicle harness to the lights. Discussions and diagnostics with Curt tech support conclude its a failed device, out of warranty. Disappointing, considering its been used for towing exactly 2 times.
