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.
Features:
Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies 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. 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. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
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.

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.Working with etrailer was great. I accidentally ordered the wrong drawbar for my hitch and they called me and fixed the order before sending it.
The hitch installation went of... without a hitch.
The only bummer was running the hot lead from the rear of the car to the front. It was kind of a royal pain.
Order arrived quickly and the wire harness was easy to install. Staff at etrailer very helpful during the order process.
The trailer hitch is just what I wanted and it works great. The wire harness makes the trailer lights work right off the battery. This keeps the lights from dimming when in use.
From the minute I discovered etrailer.com for my new trailer hitch needs, called them on the phone, got to a live person who helped me order every item I needed, was alerted that my items had been delivered, and opened the door to see a big cardboard box that actually was still in one piece, it was a topnotch experience. Talk about great customer service...wow!
I will attach a photo of my hitch once it's installed on July 29.
This kit was pretty easy to install, especially with the instructional videos on the site. It has held up very well over the past year, with absolutely no issues.

Have been using the wire harness on and off for a year on my Honda Fit. Most of the time the cables are tucked away by the spare wheel and I just pull them out, and connect to the battery, running the wire through the car when I need to hire a trailer. So far works great and is the perfect solution for me.
