Wiring a trailer doesn’t have to mean splicing into your vehicle’s tail lights. This Curt T-Connector harness plugs straight into the existing tail light connectors to create a clean, factory-style link. It’s the simplest way to get a working 4-flat connection for your trailer lights without digging into factory wiring.
Once installed, the 4-pole flat connector delivers running lights, turn signals, and brake lights so the trailer mirrors what your vehicle is doing. It provides the core lighting you need to tow safely and stay road-legal with small or mid-size trailers.
The integrated converter matches the vehicle’s separate signal and brake circuits to the trailer’s combined system. That keeps everything working together smoothly so your trailer lights flash exactly when they should, protecting both vehicle wiring and trailer bulbs.
If the vehicle didn’t come prewired for towing, this harness fills that gap. It adds everything needed at the rear of the car for trailer lighting without extra modules or custom rewiring. Just plug it in behind the tail lights and you’re ready to tow.
