Tekonsha Trailer Tow Harness Connector

Tekonsha Trailer Tow Harness Connectors: Plug-and-Play Wiring Done Right

When it comes to connecting your tow vehicle's electrical system to a trailer, the harness connector is the critical link that keeps brake lights, turn signals, and running lights synchronized between your rig and whatever you're hauling. Tekonsha has spent decades earning its reputation in the towing electrical space, and their trailer tow harness connectors reflect that depth of expertise in every detail.

A Legacy Built on Towing Electrical Innovation

Tekonsha has been a leader in electrical products for over 55 years, continuously investing in researching and developing high-performing trailering electrical components, and now offers some of the broadest vehicle coverage of any manufacturer in the marketplace. That breadth of fitment is one of the most practical advantages for the everyday installer — instead of hunting for a universal workaround, you get a harness engineered precisely for your specific vehicle.

The T-One® T-Connector: Tekonsha's Flagship Harness Solution

Tekonsha offers the largest, most complete line of plug-in T-Connectors — the easiest and fastest way to add an electrical connector to the back of your vehicle to handle the lighting requirements of a trailer. The T-One line comes in both 4-Way Flat and 7-Way configurations depending on your towing needs, and many kits include the circuit-protected ModuLite® HD Module, which safeguards your tow vehicle's sensitive electronics from trailer feedback and overload.

These wiring harnesses feature solid, weather-proof construction designed to withstand the elements and stand the test of time. Kits with the ModuLite HD Module offer a stop/turn capacity of 5 amps and a taillight capacity of 7.5 amps — parameters dialed in to work reliably with modern vehicle lighting circuits without tripping error codes or blowing fuses.

Vehicle-Specific Fitment Across Dozens of Makes and Models

Tekonsha works directly with original equipment manufacturers to design connectors and OEM replacement harnesses to make installation trouble-free. The T-One lineup covers a wide range of popular platforms, including the 2020–2026 Jeep Gladiator and 2018–2026 Jeep Wrangler, the 2022–2026 Jeep Grand Cherokee and 2021–2026 Jeep Grand Cherokee L, the 2021–2026 Ford Bronco Sport, and many other modern crossovers, SUVs, and trucks. For those needing a heavier-duty solution, Tekonsha also offers 7-Way complete kits — which mate with standard U.S. trailer 7-Way connectors and provide a plug-and-play connector to mate with Horizon brake controls.

Why Tekonsha Stands Apart in This Category

All of Tekonsha's taillight converters, 2, 4, and 5-way connectors, and adapters are rigorously tested to ensure a safe, secure, and trouble-free trailering experience. For DIY installers and professional shops alike, that commitment to testing means fewer callbacks and more confidence on the road. Whether you're wiring up a small utility trailer, a boat, or a full-size camper, Tekonsha's harness connector lineup provides the right solution without splicing a single wire.
