Wiring a trailer doesn’t have to mean digging into factory wires. This Tekonsha T-One harness uses plug-in connectors that tie directly into the vehicle wiring. No cutting, no splicing, just a clean plug-and-play setup that’s ready to go.
The built-in 4-pole flat trailer connector gives you all the basics—running lights, brake lights, and turn signals—so your trailer stays visible and safe on the road. It’s the common connection used on most small and mid-size trailers.
A powered converter is built into the harness to draw power directly from the battery instead of the vehicle light circuits. That means it keeps sensitive electronics protected and ensures your trailer lights get consistent voltage every time.
If your vehicle didn’t come with towing wiring from the factory, this harness fills that gap. It adds everything needed for trailer lighting in one kit, giving you a dependable connection point at the hitch for easy hook-ups whenever you need to tow.
