Say goodbye to the hassle of cutting, splicing, or tapping into your vehicle's wiring. This Tekonsha T-One Vehicle Wiring Harness is designed to effortlessly plug directly into your existing system. Located beneath the truck bed on the driver’s side, the T-connector quickly establishes a secure connection, saving you time and effort in getting your trailer ready for the road.
Worried about electrical shorts or overloads? The built-in circuit-protected tail light converter ensures your vehicle and trailer's lights communicate perfectly. By combining brake and turn signals on one wire, it seamlessly bridges the gap between different wiring systems while safeguarding against potential electrical mishaps. Enjoy peace of mind knowing your lights will signal properly every time.
Need flexibility in your trailer setups? This wiring harness is compatible with 5-pole, 6-pole, and 7-pole adapters (sold separately), broadening your options for different trailer types. Whether you're towing a small utility trailer or a larger setup, this harness adapts to your needs, making it a true all-rounder for various towing situations.
Built to withstand the elements, the 16-gauge bonded wire construction of this harness ensures durability and reliable performance over time. The included dust cap helps protect your connection from dirt and moisture, so you can tow with confidence in any weather conditions.
Never get stuck trying to figure out wiring issues on the road. This harness allows for quick and easy access to all connectors and electrical systems. With it installed, you will easily locate any issues without extensive disassembly, making maintenance a breeze and keeping you on the move.
No more one-size-fits-all solutions. This wiring harness is designed to be a perfect match for your vehicle, ensuring an optimal fit and reliable operation from the get-go. Ensure your towing setup is as seamless and integrated as possible for a variety of models without compromising on quality or ease of use.
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located beneath the truck bed, near the driver's-side frame rail.
Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights.
This will not affect how the tail lights on your vehicle operate.
This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.
