Features to know about

Plug and Play Simplicity: T-One Connector

Experience hassle-free installation with the T-One Vehicle Wiring Harness. This custom-fit harness is designed for easy plug-and-play installation, eliminating the need for cutting, splicing, or taping your vehicle’s wires. Simply plug the T-One connector directly into your existing vehicle wiring, and you’re ready to tow. Perfect for anyone who wants a straightforward setup without the complexities.

Protect Your Vehicle's Electrical System: ModuLite Powered Converter

Worried about overloading your car's electrical system while towing? The ModuLite power module has you covered. It draws power directly from the vehicle's battery, bypassing the factory wiring to reduce the strain on your electrical system. This innovative system combines your vehicle’s brake and turn signals into a single wire used on trailers, ensuring compatibility and peace of mind when on the road.

Weatherproof and Durable: 16-Gauge Bonded Wire and 4-Flat Connector

Face the elements with confidence knowing you have a solid, weatherproof construction. The harness uses strong 16-gauge bonded wire and a 4-flat connector with a dust cap to keep dirt and moisture out, protecting your connections and ensuring long-lasting performance. This reliable construction ensures that your wiring stands up to whatever the road throws at you.

Amp Up Your Towing: Circuit Capacities Tailored for Performance

Optimize your trailer’s performance with the T-One’s ample circuit capacities. The Stop/Turn circuit can handle up to 5 amps per circuit, while the Taillight circuit maxes out at 7.5 amps. These specs mean you can confidently connect to your trailer’s signal lights for a safe, reliable towing experience.

Convenient Storage and Access: Rear Cargo Area Stowage

No need to worry about where to store your wiring harness. When not in use, this harness conveniently stows in your vehicle's rear cargo area, ready to go at a moment’s notice. Keep your setup neat and accessible, ensuring that you can quickly connect and hit the road whenever adventure calls.

Great wiring kit and very easy to insta ll



by:

Worked as advertised! I installed the harness myself out on my driveway. Snaking the power wire under the car to the battery was tricky. Would have been easier, if I had access to a car lift, but I had a set of 1/4" fiberglass pulling rods that did the trick!

The wiring kit has worked flawlessly since I installed myself about a year ago in my 2021 Ford Bronco Sport Big Bend version.

Etrailer was very helpful very professional the only thing that was the slight bit aggravating was the usps situation of moving their office which delayed my product but it still came just a couple day later than it was sapose to



by:

I had this wiring harness installed professionally. They told me it went in with no problems. They asked me to find a plug and play harness. They were having trouble sourcing one for such a new vehicle and didn't want to do an installation that involved splicing wires on my Bronco Sport. This seemed to be the best price and option I could find. Paired the harness with the Curt 13474 receiver. That receiver leaves the OME bumper plate in place and the receiver fits below and slightly forward of the bumper, adding more metal to absorb impacts from behind. Other receiver options replace the bumper plate with no net gain in strength. I had them route the wiring for the connector into the wheelwell for the spare. When connecting to the trailer, the wires will extend out the lift gate. That way the wiring is out of weather and not exposed scrap or snag if I am off road.

2021 Ford Bronco Sport

I'm by no means a mechanic, so I was initially nervous about installing anything electrical related on my new Bronco Sport. I looked at other wiring harnesses, and they required splicing wires, which made me even more nervous. But the T-One connecter didn't require any splicing and was easy to install. I also applaud the step-by-step installation video. It was was VERY helpful. Thanks much!

Great product
Plenty of DIY info to
get it done fast.



by:

Excellent product I installed it in about 3 hours ran positive line through the wire conduit on the drivers side and to the fuse block avoiding the running of wire under vehicle as some video suggested didn’t think that was to smart anyway direct plug in at taillights no splice installation works great



by:
2021 Ford Bronco Sport

These trailer wiring harnesses are the bomb! This is my second one in 3 years and if I had more cars I'd install it in every one of them, it's a simple plug and play unit and even the most mechanical inept can install it, another great product from e-trailer my go to trailer supply company, thank you for another awesome product, you make my life so much easier!

This took care of the lighting for our litte RV. I didnt have to splice into the wiring on our brand new vehicle. The instructions were easy to follow. took me about an hour and a quarter from start to finish.



by:

Installed as easily as advertised on my Bronco Sport. The factory connectors were spot on. The hardest part was deciding how I wanted to route the wiring, and that wasn't hard at all.

my mechanic installed the hitch and wiring today. he wished there had been instructions with the wiring, but he got it done

Very nice wiring kit. Be sure to do the hitch and wiring kit before you put everything back together. Watch their very good wiring video.

  • Troubleshooting a Plug in Wiring Harness for a 2024 Ford Bronco Sport
    That sounds about right Stanley. It's either a bad ground or a bad control module. Both harnesses we have for your Bronco Sport item # TK46FR and item # C47WR require you to ground the harness out to a bare clean piece of metal with no paint or corrosion. I recommend checking to see if it's come lose or is dirty.

  • Why Does The Trailer Wiring Kit For a 2023 Ford Bronco Sport Require Connecting To Vehicle Battery?
    The power wire ran to the battery with the T-One Vehicle Wiring Harness # TK46FR is what powers the module and sends power to the trailer. This module combines the separate turn signal/brake lights into the single wire used on trailer as well as reduces power strain put on the factory wiring. Since vehicle wiring has gotten thinner to save on costs you cannot pull enough power from the factory wiring so the powered converter provides the power sent to the lights on the trailer. If you...

It will also bolt up easily to your frame as it does not require removing the rear bumper fascia for installation like some other receivers will.

Due to how different the install is, I highly recommend going with the one that is much easier, which is the Curt: - Curt Trailer Hitch Receiver # C76HR The Draw-Tite requires you to remove your tail lights, bumper fascia, and bumper beam to install, while...

  • Do I Need to Cut Wheel Well Panel to Install Curt Hitch on 2022 Ford Bronco Sport
    Great question! When we installed the Curt Hitch Receiver # C76HR on the 2021 model Ford Bronco Sport (see attached) our installer ended up just tucking that wheel well panel up next to the frame rail instead of cutting it (see video starting at about 4:00 minute mark). Shane is a great installer and I really like the work that he does so since he just tucked it up by the frame that's what I would do. You're more than welcome to cut it if you'd like, but tucking it up under the vehicle...
