Quickly and easily install a 4-way trailer connector on your Kia Sorento with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. 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.
Once installation is complete, the 4-way 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 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.

Super high-quality product at a competitive price. But etrailer’s fast service and detailed harness selection shopping tool are what drove my decision to buy here!
Joanne was knowledgeable and helpful,with a great attitude and personality.Installing the kit was very easy one thing I added was a toggle switch in the power line to turn power off when trailer lights aren’t being used,I’m really satisfied with the kit
This is the second trailer wiring harness that I have installed on a Kia Sorento. The first was on my 2012 Sorento. This one is on my 2014 Sorento. Having used the online video installation instructions the first time around and having no problems, I went straight to the video for my 2014 Sorento. The Curt T-Connector kit makes wiring easy. No splicing, just plug in the matching connectors, mount the power converter and run a few wires for a ground and forward to your battery. Hiding the wires behind the hitch as per the instructions with cable ties gives a clean look. I also mounted a Curt plug receptacle to the hitch so that the connector is not just hanging on the safety chain holes. As you can see from the photo I believe this gives a clean , professional look.
The trailer receiver was an easy installation, installing the wiring kit in a Kia Sorento was a pain.
We have been using the package for one year with no problems. Yes, I would order from Etrailer again.
My order was shipped promptly and arrived in good condition it was excactly as described.
Great Plug and Play wiring harness. Really happy with the results.
I had this installed by a mechanic. The installation is difficult if you don't have a lift and all the tools. However, once installed, the product works great. I highly recommend this product.
Looked up installation for my vehicle on YouTube.Piece of cake. Works great.
I installed the kit. It worked ok for the 2-3 times I used it. I believe on the third time I used it I noticed the running lights on one side were on in even though I didn't have then on. The brake lights and turning lights were not working. I managed to get through the short trip on that day and checked all the wiring. I hadn't made any mistakes installing the kit. Next time I hooked things up the fuse had blown. I took the vehicle to my cousin who has a business for pickup trucks. He took the taillights out and said one of the wires in the harness had pulled out. He said the wire was not secured in it's place when the harness was assembled. There was no way to see that when I installed the unit. I threw the unit away and my cousin installed another brand unit.
Been wanting to take the bikes with us camping and now we can. Thank you so much
These were exactly what I needed. The only things I wish were different was the hitch is very heavy and the bolt alignment was a little off which made it hard to get all bolts in. The wiring kit is good. If your able to put your vehicle on a lift, it would be recommended to make it easier to run the power cable. Overall this is a good aftermarket kit.
Great product!
Easy to install, I like how it isolates the electrical system and it works great. Your video instructions were outstanding. With the video a five year old could install the wiring. This was installed in my 2019 Kia Sorento. The first pix shows in the back very low profile, the second pix shows inside the engine compartment, truly cool.

Ive had no issues at all. Works great. I did bottom-out once but it was my fault, deep ravine. The hitch seems to stabilize my rear end somewhat. Dont know if its good or bad. Forgot to mention, your wiring harness is super cool and easy to install.
Wiring harness has quit working less than a year after purchase, one trailer brake light is always on, neither of the turn signals or the other brake light is still working.

It sounds like the harness has shorted out. To do a bit of trouble shooting, start by using a circuit tester to check the functions at the 4 flat connector. Also check the ground wire remains as a good solid ground to bare metal. You can then next check the signal of the wires leading into the converter box and out of the converter box. If you have a signal entering in the box and not out the other side then the harness will need to be replaced. I have a FAQ below that can help with testing the harness.

The second install - a "Upgraded" system worked great. It was a plug 'n play so I didn't have to splice, solder and tape wires. Your video and printed instructions were very clear and spot on. Screwed the flat 4-pole mounting bracket to the hitch frame and used JB Weld to bond the flat connector to the mounting bracket.
thanx,

trouble free, no problems
Nicole T was a great saver of Get to g my vehicle ready to pull my trailer. The wiring harness I purchased thru a different supplier failed to ask a crucial vehicle option. It caused the wrong wiring harness to be purchased. I contacted Curt directly and Nicole T was on the job with her "A" game. She asked the right questions, allowing me to select the correct wiring harness. She arranged shipping to ensure I receive it as early as possible, the next day. Installation was quick & easy. Thank you Nicole T.

Great, it has lived up to my expectations. Again, without Nicole T knowledge of your products & ability to ask the required information, I would have had to postpone my trip & spend additional money. Thank you again Nicole T & Curt.
Extremely helpful video on etrailer website convenienced me to purchase this wiring harness for my 2018 Kia Sorento. Every bit as easy as pie! A well engineered harness with plenty of length on the wiring and all the plugs matched. You may need additional black zip ties on hand if you’re picky like me.

Installed it a year ago. Everything still works perfectly! Be sure to watch the video before you begin installation and you will be just fine!

Good product ,worked as advertised and received on time.
Simple to install only thing I didn't use that was sent was the butt connectors. Personally don't like that style . Small issue with preference is all. Looks like it was factory done and not after like other wireing harness that I have seen or used.

Have had one issue with it in a year. My right rear marker light will stay on if I leave the in line fuse in when no trailer is connected. Simple enough fix I dont pull a trailer that much so I just pull the fuse when Im not using it. Not sure if its auto manufacturer issue or trailer wiring issue but eh not that hard to overcome

Package contained everything promised in first class quality and instructions. Fit at all points was perfect and easy to install. Supplied instructions were clear and specific. I have experienced no adverse issues with the installed wiring. Highly recommend this wiring kit. My installation was on a 2016 Kia Sorento SUV.

After one year the unit is still functioning perfectly. Quality product all the way.
Fast FREE shipping, looks as though all components are included before installation.
What I like most is the VIDEO, recalling that a picture is worth a thousand words, and having worked at Kodak for 30 years, the video takes any guess work out of it.

It worked GREAT, right up to the point when with my 5x10 utility trailer in tow, the 2015 Kia Sorento was totaled in a sudden snow squall, when a young on coming driver lost control and spun into my lane. The trailer held fast to that hitch.
The hitch and harness arrived 3 days before scheduled date and packed very well. Some minor rubbing on the tube, no big deal, I have paint. Dealer etrailer. Won’t install for another month, that review will follow then.
