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.

Quickly and easily install a 4-way trailer connector on your vehicle 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.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.
My husband said it works great. The only issue was he had to run a wire from the back of the vehicle to the front to the battery. But, that is just because of the vehicle we have no fault of etrailer.
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.
This wiring harness fit as it should on my 2021 jeep wrangler 4xe. I am quit happy with the results. There is only one item would change and it is the metal bracket that holds the 4 wire plug. It doesn't have a great design.
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 real deal. Don't waste time and money with other companies. Order what you need from here and you know it will be right.
"first impression was that this harness is pretty high quality and seems complete. as i worked with it, using the directions as needed, i felt it was easy to follow and accurate. i followed exactly what was explained for the 2 tail lights. they went somewhat smoothly, the only exception being getting them off the car. i ended up referring to several videos to get them out. what finally worked was using packaging tape attached to the long outside portion of the lens. pulling this and wedging my fingers just inside the black plastic edges on the inside. after quite a few pulls, each came loose. be sure sure to use your body as a stop, to keep the light assemblies from jerking out too far from the body, lest you break plastic or the wire connector.
for the ground and the power wires, i did things differently. basically i spliced a much longer ground wire to what was there and ran it together with the extra length of hot wire (black wire). my car has a 12V 180W cigarette type plug-in near the back on the passenger side. i opted to route the ground/hot wires behind the panels up near this cigarette plug. i cut a small hole in the bottom of the passenger light assembly plastic access panel, and routed the ground/hot wires out here nearly next to the cigarette plug. i ended up buying a fused cigarette plug and connected the ground/hot wires to it, then plugged it in. it might be nice to include a cigarette plug in the kit as i suspect all sorentos have this rear 180w outlet.
lastly, i routed the 4-pin connector wires differently too. i did not want this plug just hanging out the back of the car when in use. so, with the spare tire out of the way anyway from the hitch installation, i looked for a body plug there. i gounf 2 metal plugs about 3/4" in diameter and removed the one closest to the driver rear light assembly. i enlarged it to just barely allow the 4-pin connector to pass through (1.5" x .75"). the 4-pin connector wire are then routed and secured out of the way of the spare tire, the hitch and comes out from below the rear bumper facia besides the hitch. my trailer has a 7 blade round connector, so i needed an adapter to the 4-pin connector.
finally, the control unit is anchored with the supplied 2-sided tape below and to the right of the driver access panel. there is a flat area there that hold it securely.
... and now all camper trailer lights work as intended, night lights, brake lights, turn signals. i've attached some pics to hopefully help with the above explanation."
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.
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.
The products were exactly as described and the delivery was in two days instead of the advertised five ! I have shopped at eTrailer.com before and I will certainly do so again. Excellent company to do business with.
Couldn’t be happier! This was such a better experience than Amazon. I ordered one from Amazon originally, it took forever to arrive, and it didn’t fit. So I came here to etrailer the price was comparable, the quality is better, they shipped it faster(I payed for the 2 day shipping), it was easy to order, the online instructions for installation on YouTube were great. Next time I’m coming straight here.
Awesome. Was a simple hookup everything was as described
Right part and on time.. good price
Great, shipping was fast and came with everything we needed.
fit and finish were very nice, installation instructions spot on, would purchase again if needed
Excellent service, unbelievably fast shipping! Highly recommend etrailer for your needs!
Connector works great.
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,
bill
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.
Install was smooth and easy to follow instructions took about an hour to complete
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.
Started to mess with turn signals after about 6 months. Had to disconnect it to get turn signals to work correctly.
I purchased a 2020 Sorento and needed to tow trailers. I purchased the receiver as well as the T-connector wiring package. The wiring package was a breeze to put on, I followed the video from the web site, and had it installed in 15 minutes.
The harness connector c56256 not working properly. After installing trailer hitch looked good but the harness c56256 has problem, checked light left signal work brake light work but right signal not working.
I need to call or need nice replacement c56256 harness connector.
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.
