Say goodbye to the hassle of cutting, splicing, and tapping wires. The T-One Vehicle Wiring Harness with a 4-Pole Flat Trailer Connector is custom-designed to plug seamlessly into your car's existing wiring system, ensuring a perfect fit every time. No more guesswork or complicated electrical setups—just a straightforward, reliable connection that gets you road-ready in no time.
Guard your vehicle and trailer against potential electrical issues with the integrated circuit-protected converter. This robust feature is a lifesaver when it comes to protecting your vehicle from electrical shorts and overloads, allowing you to tow with complete confidence and peace of mind.
Most trailers operate on a simpler two-wire system, but your vehicle's three-wire setup could make things tricky. The built-in tail light converter elegantly combines brake and turn signal functions onto a single wire, ensuring your trailer’s lights work precisely as they should without affecting your vehicle’s tail lights.
Keep corrosion at bay and ensure lasting reliability with weather-resistant features. The harness comes with a dust cap for the 4-way flat connector and is designed with 16-gauge bonded wire, offering durability and protection even in adverse conditions. Add a dab of grease to the connections to safeguard them from the elements.
Whether you’ve got a 5-pole, 6-pole, or 7-pole trailer adapter, this harness has you covered. With its flexible design, it easily adapts to a range of connector types (sold separately), making it an ideal choice for versatile towing needs, no matter the trailer configuration.
With comprehensive installation instructions available, most users will find they can install this wiring harness themselves in under an hour with minimal tools. Whether you're a seasoned DIYer or a first-timer, this harness empowers you with the independence to get the job done quickly and efficiently.
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove some interior trim or carpeting to access the harness.
Once installation is complete, the 4-way flat connector will be stowed within your trunk.
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 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.
