Installation
This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located along the frame rail at the rear of your vehicle. The exact location of the port will vary depending on the make, model, and year of your vehicle. Once you've plugged in the connectors, insert the included fuse into the in-line fuse holder.
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 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.

It worked perfectly for my 2016 Hyundai Santa Fe that HAS the trailer package. I think that package was an option and may not be on every vehicle. It plugged right in to the wiring harness under the driver's side of the car at the back of the vehicle. You have to remove the plastic panel next to where the trailer hitch mounts. It worked perfectly first time, and it saved a ton of time. Well worth it.
Daniel J - 09/05/2021Plug & play for 2020 Kia Sorento. Dinged a star because the trailer connector does not fit the extra bracket well. It does not appear to have been designed for a bracket mount. I had to force fit and secure in place with a zip tie.
I was very happy with etrailer.com The items were delivered in 3 days. The wire harness was an easy plug and play. And mounted nicely to the hitch wit items the short mounting bracket and 4-Pole mounting bracket.
Quick and easy installation on my wife’s 2018 Santa Fe Sport Ultimate 2.0T with factory Tow Prep package. I did this as part of installing a Curt hitch, and it was an easy plug and play connection, then just tuck the wiring away and secure with cable ties. Couldn’t be easier! I also installed the “ 4-Flat Universal Mounting Bracket” from etrailer, and it ties the installation together nicely and looks very tidy like a factory installation (I’ve always thought dangling trailer wiring looked sloppy).
Great experience from start to finish. Quick delivery. Perfect fit and easy to install within 30 minutes. Routing the wire harness was a bit challenging but it also was a perfect fit. I only have one picture but you can't see the hitch since it is behind the center panel which is exactly what I wanted.
Brad O - 07/23/2015I recently bought the Curt receiver (p/n C13153) and Tekonsha 4-pin harness (p/n 118269) for use on our new 2017 Hyundai Santa Fe Limited Ultimate. We use the hitch to tow a small utility trailer occasionally, and more often use it with a hitch-mounted bike rack. I also ordered a mounting bracket kit and companion adapter plate since I had hoped to have the 4-pin connector mounted to the hitch (v. just zip-tied, etc). For installation of the receiver I dropped the spare tire since it is easy and helps for maneuvering the receiver into place. I did not lower the exhaust. I cleaned the tapped holes in the frame with a spray lube and wire brush prior to mounting, and I think this is a necessary step since a couple of the holes were pretty gunked-up. I checked by running the M10 screws in prior to putting the hitch in place, which I also recommend. I did not have a 2nd person available to help put the receiver in place to install but I had success using a floor jack and a piece of 2x6 to lift the receiver into place and start all the screws. It took a little patience to maneuver past the exhaust but really the fitment of the hitch is very good and it wasn't a bad struggle. A helper is probably the best way to go. As others have said, the videos provided by etrailer.com are really helpful. I finished the hitch installation by torqueing the screws and installing and torqueing the carriage bolts. It is a bit of a job (at least for me) to get the proper torque for the carriage bolts when laying on my back like that, but the overall connection seems super-secure. The spare tire did not interfere with the receiver after installation, though as you'd expect the clearance is small. After the receiver was done I installed the wiring harness. Once again, the video was really helpful and everything went quite smoothly. I found I needed to supply a few of my own zip-ties to secure the wiring to both the hitch and the factory wiring bundle since the provided ones were too short. After this I attempted to mount the 4-pin mounting plate to the hitch but I could not find an orientation that I was happy with and which would not interfere with the removable trim cover for the hitch. On the other hand, I found I was satisfied with leaving the 4-pin connector hooked to the check-chain hole in the receiver, so that is how I will leave it. After finishing the installation I hooked up our trailer. I found that there is a good amount of space in the check-chain openings, at least for our trailer, and the wiring connection (trailer lights) worked perfectly. When I went to install our bike rack I was a little concerned about the space around the hitch hole for the head of the bolt, but when I installed the hitch and anti-rattle bolt the fit was fine. Overall I'm quite happy with the hitch and wiring harness and I'm looking forward to many years of use. As always, etrailer.com was great to deal with and I would always recommend them to anyone looking for towing equipment and accessories.
This is my second hitch I purchased and installed. Both were great and the instructions for installing were spot on. My only complaint is that it is disappointing that the hitches do not have a nice integrated trailer light hook up. It’s a crappy bolt on or zip strip unsturdy light hook up. It doesn’t look nice after installed. And are very flimsy.
I received all of the products I ordered. I installed them today and everything looks great and operates properly. Very easy to install. Highly recommended. Videos for installation were great as well.
Jimmie L - 07/23/2021Kia dealer installed the original 4 way flat trailer wiring 2 years ago. The tester showed 2 dim lights before I ever used it. Disregarded the dim lights and added the ignition 12V and brakes control wires to a 7 way Bargman connector. I had running lights without anything on which worked only 2 times. Then no right brake or signal flash. Removed the factory Kia 4 way flat and observed no fuse! THEN I ordered the eTrailer equivalent WITH a 15 amp fuse. The tester looked good with no lights initially then the brake, running and turn lights tested fine. Hooked up and tested fine also. Happy customer!
Archibald S - 01/29/2021You are all amazing. You sent a great product and you made it so easy to follow. Unfortunately for me...when I pulled down the panel under the car to connect the wiring...my Kia did not have one there to connect to. I will have to take it to the dealer for them to locate where it actually is.
I bought this converter kit since I was adding a hitch to my 2014 Santa Fe. My Hyundai came from factory with the towing setup and the plugs for this were already present. The installation was pretty much cut and dry. The price I paid for this kit was much less than what [vehicle manufacturer] wanted for theirs and they even look identical. I have the light output plug connected to a 4 pin to 7 pin converter since I pull a popup camper and a 12' enclosed trailer. So far I have not had any issues and I do not for see anything going wrong with this kit.
AJ - 08/31/2020Plug and Play on my 2014 Kia Sorento. Plugs right in to the factory pre-wired harness plugs located under a cover behind the left rear wheel. Mounted the electronic box underneath also with a little silicon adhesive on the back. Easy install. Cable tied the rest of the wiring in the bundle as you can see. Fast easy ordering and shipping as always. It's nice to click on the link in the email they send and go right to the tracking page with the map that shows progress and the details as well. Some sites make you log in again for the same information. Not a big deal, but as you know it's the summation of all the little things done well that make for a good purchase experience.
It's easy to install. And also the electrical recommend the exhaust pliers.
Mark T - 08/21/2021Received my Curt custom hitch and wiring harness and had it installed in a hour. There was no need to drop the exhust, I just had to bend the bumper alignment pins down a little and lower the spare tire. The wiring harness was plug and use, so it just required zip ties to keep the wires up and off the exhust. I love the look and fitment very much. If I had anything negative to say. It would be that I wished the 4 pin wiring plug had a bracket to hold it instead of zip ties or just letting it hang. Which I will be buying one and installing it as well. But overall pretty happy with my purchase. Thanks
The wire harness is easy to install and is plug and play. The enclosed instructions are detailed, but easy to follow.
Super easy! I was able to change the wiring harness myself in less than 5 minutes. It was simply unplug the old one and plug in the new one and everything worked perfectly. I highly recommend!!
Laurie L - 04/12/2021 Laurie L - 04/12/2021I called etrailer on Thursday and ordered my trailer hitch and electrical for a 07 Hyundai Veracruz. Ashley couldn't have been more helpful. I got my hitch on Saturday. Put it on with help, in about 2 hours. Everything was what was explained. Already took the boat out. I couldn't be happier.
perfect fit. saved me a couple hundreds
Third time I have used you in the past couple of years, Have not had a chance to install my latest purchase . Received my hitch in 4 days with wire package for trailer lites. Only negative was the box had worn through where the mounting plates are. Would recommend a few more securing tabs to keep the hitch secure in the box. You will be hearing from me on my next purchase. Your system for looking up items is very good and easy to use. Thanks again for a good experience.
After Katherine B sorted out which wiring harness I needed for my 2019 KIA Sorento Ex (which neither the KIA factory or local KIA dealer could tell me) the rest was easy! I watched etrailers installation video just to make sure I did it properly and used the tester to double check all the lights functioned. etrailer customer service is second to none, thanks for your patience and help!
Ronald C - 03/24/2020Good instructions came with the package and it plugged right in to my Santa Fe's existing wiring. And the YouTube videos on the e-trailer site are great!
I initially got the wrong wiring for my etrailer hitch but after contacting the customer service section they corrected the problem right away. Thank you Jennifer B with get service! .
I installed this on my vehicle one year ago. Installation was easy, and the product works as it should with no problems.
This wiring harness was a homerun. Plugged in and works as expected. I have a 2013 Santa Fe Limited
Easy plug and play. I wish i knew that there was a separate mounting bracket that I should have ordered along with it.
