Not every car or truck comes equipped and ready to tow, which is why Tekonsha offers a wide selection of OEM style T-Connectors so that you can turn your car, truck, or SUV into a towing machine! The Tekonsha T-Connector Wiring Harness offers you a simple plug-in solution for connecting your trailer lights into your vehicle's wiring. All T-One connectors come as a complete one-piece harness with a cover and include a 4 pin flat plug with a cover to protect it from the elements when not in use. Tekonsha uses 16 gauge wire and there is no cutting or splicing required, giving you an OEM appearance.
