Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs into OEM tow package wiring harness. Powered converter reduces strain on wiring system. SMT construction ensures superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, on the driver's side. Once you've plugged in the T-connector, insert the included 10-amp fuse into the integrated fuse holder.
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 tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
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 the trailer. This converter combines 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.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Bought this to replace the same model that developed a problem where my turn signal lights on one side of the vehicle would not turn off. Installation is relatively easy but it's hard to get the box mounted to where it does not move or fall off. Other than that really minor item. It works well.
excellent plug and play ! Great service . I ordered the hard wire from the battery version but saw the quick plug when I started to wire . called etrailer and they sent the factory tow package immediately . No problems.

Worked great till the car was totaled . I pulled it out and gave it to my Brother in Law for Hyundai . Works great on his .
used it one time pulled my boat 2 blocks. they made the install so easy a 5 year old could do it, I traded this SUV for a truck as it is easier to haul things and with that I bought the dual 4 and 7 trailer harness with the same ease to install with no. issues
Hello, I am very pleased with the ease and quality of this wiring harness. The way this is designed, with the proper connectors that connect directly to the factory conectors, was super easy to install with no splicing of wires. As for the Hitch itself, again, I am very pleased with the quiality of the unit. I would definitely recommend having 2 people for the install and proper tools, unless you have a Hitch rig to be able to do it yourself. To have a Hitch such as this installed by someone else would have cost hundreds more, I have checked.
Fit existing wire harness plug in perfe ct
Wiring harness does as expected and was a easy connection/install. The video where to locate factory tow plugs and how to takedown panel was a asset making for quick process. Tested all function post install everything good ready to now haul with my Sorento.
Dealing exclusively with the product, the product is of high quality and fits perfectly. Backup support with the company is excellent and thorough. Shipping time is absolutely terrible. As being in Canada I was very disappointed in the fact that it took so long for me to get it. On top of that, even though this product is possibly made in the United States, and under free trade should be duty free I had to be duty charges on this. In my case I have the availability to have it shipped to a US address and should have taken that.
i cant add to what is already known about curt products...iv'e been buying them for years...this hitch and wiring set up is top of the line...it took me 10 min to install the hitch..that incl getting it out of the box...the wiring harness...boom plug and play baby!!

a year later..its all good...curt is made to last..
Very easy to install on a 2019 Kia Sorento with the factory tow package. It plugs right into the factory connectors. For the 4 Pole Flat connector I used bracket 18144 since the wire is fairly short. It looks clean and professional. This bracket attaches directly to the no-drill bracket already present on Draw-Tite hitch receivers.
To check if your vehicle has the tow package you just need to pop out the 2 plastic rivets on the driver side panel shown in the install video and see if the 2 connectors are present. I was not able to confirm through the dealer or Kia corporate which Sorentos have the factory tow package.
Easy to install, really appreciated your instructional videos
Made the electrical side of it a snap
Your provided instructions on finding connectors connections on our 2019 KIA Sorento, proved to be exact and very clear. The combined order of Curt Wiring Harness and Curt Trailer Hitch, was promptly and properly received today, and using your videos, both installations were accomplished with regular hobby hand tools to a perfect fit and fast results. NOW we are looking for a suitable boat to hit the water! THANKS FOR ALL YOUR GREAT HELP!
The folks at e-trailer were absolutely great in helping me identifying the proper harness for my new 2016 Sorento. Once ordered it came in a few days and installation was a breeze. The online video was great at explaining the installation process - much better than a handful of printed pages and diagrams. Once the access panel was removed and the factory caps removed from the prewired connections it was effortless - about 20 minutes start to finish. Everything worked perfect during the post installation check - Well done etrailer.
Exact fit and easy to install. Video instructions make it easy
The site was easy to use and search for what I wanted and needed. In addition, the DIY videos on the etrailer.com site gave me the confidence to complete the install. From installing the hitch receiver to the connection of the 4-pole wiring kit(hint: if you're vehicle has the prewiring for towing, they have the custom kits to match). Install was a snap, like 5 minutes, due to the exact fit of the product. It took out the unnecessary problem of figuring out the wiring. Thanks for everything etrailer.com! You definitely found a new customer and I will be highly recommending this site to my circle of family and friends.
Part was super easy to install with the quick-connects. I especially appreciate the thorough installation videos. Wiring needs to be routed through a small hole in the rear of the bumper frame on the passenger side that is impossible to see and very difficult to feel out (2008 Hyundai Veracruz), but with patience and determination, you'll figure it out; watching the install video helps you find your bearings. I was disappointed in the shipping speed (or lack thereof rather) as it took a little over a week to arrive.
Trailer hitch and wiring kit were a “perfect” fit. All holes lined up properly all necessary nuts/bolts provided. Videos for installation are very helpful and provide clear views of all the key issues for a simple professional installation. I found the paper instructions for both confusing and poor quality graphics. Video the only way to go! My experience with initial ordering, delivery and follow up questions were very good. These folks really know what quality customer service is as well a produce an excellent product.
Excellent product. Worked with n
Your videos made it possible. Though I must admit ….I’m not mechanically inclined… took me a bit more than half an hour to install (I lacked screwdrivers…lol).
The wiring harness worked great and the videos helped a lot. I did fry the fuse testing the connections but only because I had my tester set on a much higher amperage than it could handle and the fuse worked like it was supposed to. Was truly plug and play once I gained access to my already installed equipment.

Still working great. We use the hitch all the time but not so much the wiring harness. I wish larger bike racks came with built-in brake and turn signal lights that I could utilize my harness for but thats another subject all together.
Very satisfied customer videos for exact wire harness with exact vehicle make is super easy and felt very confident installing myself following the videos provided.thank you etrailer.
This makes six times I done this now and wanted a premium product for this install......at a modest price. Curt and etrailer. com came through for me. While installation instructions were straight forward, I chose to have my mechanic install rather than crawling around on the driveway. Had nice comments from mechanics on quality of the product.
It was super easy to install. I watched the tutorial video on the website and installed it by myself in about an hour. I was impressed on how heavy duty it really was. I also bought the plug and play wiring harness. I will be testing it out today.
I ordered a trailer wire harness for my 2007 kia it simple to install etrailer gives you videos on how to install products which is great and their products prices are great I would recommend them to everyone !
The wiring harness works great and was a perfect fit for my 2015 Santa Fe. The installation was straight forward and fairly simple. One problem was the double sided tape must have been sitting around for years, and was no longer sticky. I had to improvise with glue.

I wanted to ask if the issue with the lights is still happening? Typically, you will want to check your ground on the trailer and the vehicle just to make sure that the it has not loosened and is still good. It could also be that the harness has been overloaded which may mean a new harness over. It could also be that the trailer has LED lights that can be powered by low-level residual voltage present at the 4-way plug. You would see both lights light up if this was the case.
