Installation
This custom-fit T-One connector plugs into your vehicle's junction box, which is located in your rear cargo area, behind the driver's-side trim panel in the spare tire compartment. You will need to remove any cargo nets and the cargo floor hatch your paneling to access this harness. Once you've plugged in the connector, insert the provided fuse into the vehicle's junction box.
Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your jack storage compartment.
It is recommended that you use a small amount of grease on all electrical connections - the plug 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.

Powered ModuLite reduces strain on wiring system.I purchased a trailer hitch setup for my Acura MDX. The instillation went smooth and I feel confident to pull my trailers with it. etrailer was a pleasure to do business with. 757224
The T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector is the easiest harness I have ever used. In all fairness, the Acura MDX with it's pre-wired connector and separate fusebox simply make the job that much easier. The harness from E-trailer is really good quailty. I honestly completed the job is less than 5 minutes! The instructions were OK, but I also utilized their videos to get a little better insight on the job. The E-trailer website and ordering process was a breeze and the package even arrived a day early. Would have ordered from [site] but they are beginning to get so many knock offs, I decided to go with e-trailer so I would get the "real" thing. 339048

Item was packaged great. Instructions were plain enough to get the job done. A couple more specific pictures would help, but it's not bad. The kit as a whole is extremely nice and easy to install. Do it yourself, you won't regret it and you'll know it was done with care. 845531

Very easy to install and good quality 817458
We have a 2020 Acura MDX Tech AWD and on our model we did not need the 10 amp fuse no spot for it but other than that the instruction were clear and easy. Maybe took us 10 minutes. We also installed trailer hitch took no more than 30 minutes the hardest part was getting it over rubber grommets. When I use the term “us/we” I supervised my husband may have taken less time without my supervision. 815155

etrailer really made it easy. The instructions were straightforward and install was done in a few minutes. 766808
I bought the trailer hitch for a bike rack and the hitch silencer to stop the rattle of my rack. I added the wiring harness mainly because it was so simple to install and I might need it in the future. In a nut shell, you had every thing I needed at a fair price and excellent quality. My order was shipped and delivered quickly. The videos on you website are the really the icing on the cake. This was not my first purchase from etrailer and I will always look at your website first when I need something for my vehicles. 722774
