Installs Without Cutting or Splicing: Plug-In Harness

Wiring up a trailer doesn’t have to mean digging into the factory wiring. The Tekonsha T-One harness plugs right into the existing connectors, giving you a 4-flat trailer plug without any cutting or splicing. It’s a clean install that keeps the factory wiring intact and ready to go.

Built-In Powered Converter: Reliable Signal for Trailer Lights

This harness includes a powered converter that draws power directly from the battery instead of the vehicle’s lighting circuit. That setup keeps trailer lights bright and consistent while protecting sensitive electronics from overload. It’s dependable power that works every time you hook up.

Hidden Design Keeps Things Tidy: Out of Sight, Out of the Way

Once installed, the wiring stays tucked away behind panels and trim. Nothing dangles or shows when you’re not towing, so you keep a clean factory look. When you need it, just pull out the 4-flat connector and you’re ready to plug in.

Ready for Vehicles Without a Tow Package: Complete Setup in One Go

If your vehicle didn’t come with a tow package, this harness gives you everything needed to add trailer lighting. It supplies the proper circuits for running lights, brake lights, and turn signals through a single 4-flat connection—simple and complete with no extra parts to chase down.
