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 interior trim panels in your rear cargo area. 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 flat connector will be stowed in an out-of-the-way location within your cargo area.
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.

Just what I needed made putting trailer lights on my Venza very easy. Have used it many times with no issues. 312209
So about a year ago I bought a reciever hitch, receiver cover,euro style ball and wiring for my 2010 Camry to tow a 4x8 foldable trailer for powersports......Installation was straight forward and dedicated an afternoon for install.....Directions for the products was easy to follow for both products.... so far the wiring is just as I installed it and the hitch is holding up great, you can barely notice that I have a hitch back there. I think it blends in nicely....I anticipate many years of worry free towing.... Customer service is top notch also ???? 825589
Worked perfectly! Install was super easy. Great product 809154
The item worked OK only once, the first time. I have done some testing. There is continuity from battery to unit. There is continuity from unit's ground to trailer plugin. The lights on the car work fine with the unit's wiring: it gets feed from car controls. The unit is fully sealed so I cannot test continuity from unit to plugin, other than mentioned ground connection. Visually the wires from unit to trailer plugin are fine. I highly suspect the unit itself and not the wiring. I have tried the suggestions online to unplug power to it for some time to no avail. Needless to say, poor rating. 805248

Bought wiring and full setup for my Camry XLE. Directions were very thorough and straight forward on everything. Quality products, it's held up good and been very useful! I pull a small trailer and sportbike for hundreds of miles, and haven't had an issue yet. 773052

Easy installation, have had no issues 677874
This was truly a great investment! Easy to install. I watched the video that etrailer has on their site and about an hour later I was done with the installation and about another 20 minutes securing the wire to the battery for a (2015 Toyota Venza). Looks great on the vehicle. No altering the rear bumper at all. Thank you etrailer for making this a very simple task. 676976
The product itself seems durable and well crafted. The install is mostly straight forward and easy to do however the instructions are not very great. The videos on the website were not helpful for me as they were not my make and model. The greatest difficulty of the install was the running of the wire to the battery and re installing the trim. In my Mitsubishi Outlander I was not able to find a way to run the wire along the outside nor did I want. I ended up running it along the harness but once I got to the dash I could not find a way to get to the engine bay without having to remove the whole dash which I wasn't going to do. After investigating for an hour to find a hidden pathway I just ran the wire out the door and through the quarter panel. Took me about 4 hours to install. 675029
High quality product, exceptional customer service. Fast arrival. 673899
The product I received came promptly and in great condition.However, upon purchasing the products I spoke with a chat specialist who ensured me these two products were everything I needed to tow my pop up.My dad came over and informed me I cannot tow without a ball and reciever which I did not order because I was told I had everything I needed.Luckily he has the products I need.I would just educate the chat agents a little more on the products.Other then that..no complaints .You guys are great. 669166
I have used this several times and has never let me down yet. Previously i purchased a competitor brand, i towed my trailer 4 times and it stopped working. Ive had this wiring harness for a year or so and its still working. I recomend it to all. 665316
Outstanding order process. Found everything I needed for a simple trouble free install of my trailer hitch and wiring kit. This is my second trailer hitch and wiring kit purchase for a second car. Both purchases were super easy and included easy to understand install instructions. You won't be disappointed with your purchase. 646370
The wiring kit is complete and installation is foolproof. Once installed it works exactly as it should. If you are installing it in an Outlander PHEV, here are some observations you might find useful: The battery is in the rear of the vehicle and obstructs your exposure to the driver's side wiring. You might want to consider removing the battery entirely so the trim panel can deflected a bit more. The tail light wires have very little slack and the connectors are a bit difficult to pull apart. I found it helpful to remove the lens assemblies from each side and access the wires that way. Simply remove the two screws and firmly pull the entire lens straight back until it releases from the plastic "C" connector. 640705
Anyone makes you happy when things go right. I have ordered many times from etrailer.com. on this occasion there was a shipping problem. Etrailer.com immediately responded to my email communication and very quickly had a replacement item shipped to me. Great communications! Great problem resolution! Great place to do business!!! Thanks again. 638930
