Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area.
Once installation is complete, the 4-way flat 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 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.

Speaker 1: Today we're taking a look at a T1 vehicle wiring harness for factory tow packages. This product fits certain years of the Hyundai Santa Fe. To ensure that it is a fit for your vehicle, you can always use the vehicle fit guide which is located at etrailer.com. It provides a four way flat trailer connector at the back of your vehicle and to power your trailer's signal lights. It is designed for use with the factory tow package and it is compatible with five pole, six pole, and seven pole adapters. Adapters are sold separately.
Comes with a dust cap here for the four way flat connector; that way you can cover up the connection points when the plug's not being used. The black box is the included modulite. This ensures that your vehicle's wiring matches that of your trailer's. The power module connects directly to the vehicle battery through the wiring system to avoid overloading your vehicle's electrical system. It connects quickly and easily.
You don't have to worry about cutting or splicing any wires. Just locate the connection point beneath your vehicle on the frame rail and plug in the custom connector, and then you can secure the wires up and out of the way with the included cable ties provided in the kit.Then you'll also need to mount the converter box to a safe, out of the way location. You can do that with the included screw or you can do it with the included double sided adhesive foam tape. Now once your installation's complete, the four way connector will be stowed beneath the vehicle near the trailer hitch. We do recommend using a mounting bracket to keep the connector secured and easily accessible near the hitch.
It's also recommended that you use a small amount of dielectric grease on all electrical connections, like the plugs on the vehicle and the four pole connector, to help prevent corrosion. That is sold separately and available at etrailer.com. The maximum amperage for the stop and turn lights is five amps per circuit. For the taillights it's 7.5 amps per circuit. That's gonna do it for today's look at the T1 vehicle wiring harness for factory tow packages..

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 - no cutting, splicing or tapping required. Powered ModuLite reduces strain on wiring system.The trailer hitch and wiring harness was as described. I was able to install both items myself after watching the installation videos. The items arrived on time and undamaged. I would purchase from this seller again. I had a question about my order and their customer service was able to take care of my issue without transferring me to other agents. Overall, I received excellent service.
Have had the hitch for a year and use it regularly to tow my fishing boat (and several U-Haul trailers). Easy install from good instructions and it looks as good now was when first installed. The paint is not showing any wear.
Quick delivery, arrived intact, nice to have the extras in a separate box.
Fitting went well, put vehicle up on ramps for more clearance.
One tip, once you have all bolts in, just run lowers in to pull hitch up to body, do not tighten, I did and there was a small gap between side plate on one side and wasn’t pulling up even with a lot of torque, loosened bottom bolt slightly and side torqued up nicely.
Bracket makes for a “factory” look.
Wiring was easy, made sure the control box was tied with wires facing down and tied it to factory plug which was above the hitch wiring plug.
Zip ties are too short to go around hitch, so get yourself a few longer ones to save joining.

Still where I put it and no issues.
I've purchased two trailer hitches from etrailer, plus wiring harness, etc. What a great experience. The instructional videos are second to none. I wish all companies were as good as this one. Great price, awesome products, fast delivery, excellent customer service. What else can one ask for. Trust this company, they won't steer you wrong, and once they make a deal, there are no unexpected hitches! ;-)
The wiring harness was an exact match for my vehicle

The wire harness was a perfect fit and has performed perfectly, it was easy to install and the directions were easy to follow.
Couldn’t have been much easier. Remove the plastic cover under the left rear of the vehicle (3 push pins and 2 14mm plastic nuts), remove the cap on the factory harness, plug in the new harness and secure the wires as you see fit. There’s no instructions for wire storage or how to route them, but it’s very simple - use common sense - plenty of YouTubes.
Great purchasing experience! Love the do it yourself Videos! Makes installation very easy.

This product has lived up to all expectations!!
Looking at the online video showing a similar unit from U-haul...a metal clip that holds 4 way wiring connector was present and made it easier to support the unit. However, the unit I got from etrailer did not contain that clip. If this was a mistake, I would hope that clip is available.

Hi Chris, Thank you for your review. This wiring harness does not come with a mounting bracket. If you are looking to install one, I would recommend the Mounting Bracket 4-Pole Flat, product 18144. use the self tapping screws to attach it to the plastic bumper or the nuts and bolts to attach to the vehicle frame or metal bumper. If you do not want to screw into the bumper or frame, then I would recommend the 4-Flat Universal Mounting Bracket, product 118149. This one will come with zip ties that will secure the bracket to the hitch.

Very well as expected.
The wiring harness was exactly as described. Installation was quick and easy, and it works flawlessly.
ordered tow bar and harness from etrailer. got it very fast and staff knew what they were talking about' set me up with the right package.went on no problems would recommend them to anyone.
I picked the Curt trailer hitch over the etrailer hitch because it sticks out further past the bumper. I have the Thule T2 Pro XL bike rack and wanted to make sure I have enough clearance between the bike rack and the back of my 2020 Hyundai Santa Fe. Even though, your video shows enough clearance (1 1/2 inches ) with the etrailer hitch, with the Thule T2 Pro XL bike rack on the 2020 Santa Fe, I wanted more clearance. With the Curt hitch installed I have 3 inches between the closest point on the bike rack and the back of the SUV.
The installation was straightforward and easy. We did use a lift which made it much easier than the previous installation I did laying on the ground under our Honda CR-V. For that SUV I got the etrailer Hitch.
I followed the instruction video for the wiring harness, and it was a simple installation.
It all worked great, your installation videos were what made it possible for me to install the hitch and wire harness on my 2023 Hyundai Tuscon. The hitch fit perfectly the bolt holes lined up. The hitch was flush with the care frame there was not a MM of space between the hitch and car frame (see pic's) Note the hitch shipping box was damaged and had a hole in. But the wire harness did not fall out (see pic's)
Simple to use web site, fast shipping. Nice product, good quality build. Application choices are good.

Ive had no problems with the product so far. It was very easy to install and straight forward.
The Curt trailer hitch receiver works as advertised. Would recommend
Easier than video of installation. Locate the cars wiring harness, unplug ; then open and plug up new product with one snap, and secure wire line along installed mounted support to flat surface and stick-on square box. Then continue securing wire line on other side of hitch and finally mount any excess wire to hitch while leaving short piece free to serve as connecting 4 post receptor. Over and done with. Thanks for being true to your easy promise
video is spot on for installation. this is third hitch from you guys! So simple for DIY people and quality has been great! Would not hesitate to recommend, and I do not say that lightly.
Bought this with this the etrailer brand hitch for my 2022 Hyundai Santa Fe Calligraphy. Easy plug and play install. Wiring harness package was missing when the hitch arrived as the box had popped open and it most likely fell out. Customer service had a replacement in the mail the very next day. Thank you!
I am so glad I came upon the Curt trailer hitch receiver. It's exactly what I was looking for because it actually has the crossbar tucked behind the bumper and all you can see is the receiver! And the T-One harness was easy to install and works great.
Easy installed and after being used over 100 times in one year, NO PROBLEMS.
I WOULD order from etrailer.com again.
This trailer wiring kit was the exact match for the existing plug and play wiring underneath my 2020 Hyundai Palisade. However, you will need to order a separate bracket available at etrailer also to attach the trailer 4-pin connector plug to either the hitch or bumper fascia. I attached mine to the fascia pictured below.
Harness easy to install actually had alot more wire than needed. I understand Hyundai has now issued a recall related to their factory towing harness, who supplies this harness are they similar or the same supplier.
This was extremely easy to install. The majority of time is spent deciding how you want the wiring ran over to the hitch. Hooked it up to a trailer and all lights functioned correctly.
Plug and play works well
This hitch is great! I installed it myself with basic tools. The wiring harness made it easy.

Another year later and the hitch still looks good with regular use towing my fishing boat.
