Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.

Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the tail lights on both the driver's side and passenger's side. You will need to remove the protective covers to access this harness.
Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.
Once installation is complete, the 4-way 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 ModuLite power module is built into this T-One connector. With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Hey! I got the wiring and hooked it up myself on my 2022 Bronco 4-Door. Everything works great! Thank you so much! :)
It has arrived, and the package is solid. Might take me a week to find time to install so I can’t speak to that. It was a little delayed, but that was no fault of the company, but the fault of the US postage service. Looking forward to installing it.
Easy install and works as it should for non-led tail lights on the bronco base. Will need extra zip ties for clean routing down the frame of Bronco.
This Installed easily with some knowledge of vehicle wiring. Worked well with my Bronco with the non LED tail lights.
I was able to get this to fit the 2022 ford maverick by shaving the ears on the connector housing. It was basically plug and play.
Fast Shipping!
It's been one year, and no problems with this unit at all very pleased thanks,e-trailer.
No problem at all
Seems like really good quality stuff. It is a little more work then just t-inh off from the existing wires but they give pretty good instructions
Perfect fit and directions
fits good
Good directions. Much easier to install on a lifted vehicle that’s for sure.
