Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connectors plug 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. The connection point for the 4-way tow harness is located behind the driver's-side and passenger's-side tail lights. Once you've plugged in the converter, insert the included 10-amp fuse into the integrated fuse holder.
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.

If there were about 6” more wire on the pigtails going to the lights, I’d give it 5 stars.
There isn’t much room to work under the car already, and having ‘just enough’ wire makes it challenging. Super simple install. Just would prefer a little more play in the wiring.

Does NOT fit my 2025 Kia Sorento Hybrid as I was assured it would. I now have to try to source the right one, again, plus return this one for a refund if even possible.

This is a custom fit harness for the 25' Sorentos, the only thing I can think of would be if your vehicle does not have LED tail lights this product will not work for it. It is only intended for vehicles with LED tail lights. I recommend double checking to see if you do or do not have LEDs.
etrailer was quick to resolve my issue due to Curt incorrectly showing their 56474/C99DR as being for LED when in fact for the 2024 Kia Sorento X-Pro it is the 56530/C63RV. Following is my original feedback on the 56474/C99DR which helps to explain how I came to this finding.
This post may be long but I wanted to figure out why I ordered the part number that etrailer and Curt shows as the correct T-Connector for our 2024 Sorento X-Pro w/LED (56474/C99DR) yet the T-Connector plugs are different than what is on the car (blue plugs are Curt connectors). First I confirmed our car had LED by the window sticker. Then I pulled the right side tail light and found the KIA part number (RS5600) and validated that number on the KIA parts website. YES, we have LED tail lights. I then went to the Curt website to confirm/validate their info and what part number they show works with the 2024 KIA Sorento LED (non-hybrid) and also confirm the plug configuration that aligned with what our KIA has.
SURPRISE, Curt shows part number 56530 with the same plug configuration that matches what is on our car but also shows it as ‘excluding’ LED, even though our car has LED. They show the 56474 as the part for Sorentos ‘with’ LED. This is what I ordered from etrailer and discovered was wrong for our 2024 Sorento w/LED. As I explained to Lauren at etrailer, I'm pretty OCD and do my due diligence prior to ordering and was positive I ordered what both etrailer and Curt showed as the correct part (C99DR/56474). She also said her system showed 56474 as being the correct part. The only concern I had was even though I confirmed prior to ordering my window sticker showed LED tail lights did I truly have LED, which I confirmed per KIA part number. I ended up having to reorder the correct connector (56530/C63RV) but feel this was NOT my, or etrailer’s, issue but what Curt shows incorrectly and etrailer just passes along. The packaging I received also showed it had obviously been opened and returned, most likely due to the same issue I had; wrong part. So, hopefully this write-up will help someone and also stress you need to pull a tail light and check the plug configuration to ensure you are ordering the correct T-Connector with the same configuration. This was the one step I didn't do and it cost me time and more money since I have to pay for shipping again. Giving one star since I ordered what eTrailer showed would fit and it does not. Now that I have done and documented the issue hopefully eTrailer will fix their website and also inform Curt of the issue.
I have a '24 Kia Sorento. I was assisted by a CSR on the phone when I ordered my hitch and wire harness. The harness ordered was incorrect, C99DR per website. Correct harness is C63RV which has the correct connectors. The website is incorrect. I returned the first and had to reorder the correct and paid an additional $16 shipping and had to make another install appointment at an additional cost.
This harness makes wiring easy. My installer really liked it.
This was not made for my 2025 hybrid kia carnival. Doesn’t fit waste of money and time ??????

Unfortunately, this will only fit the non-hybrid versions of 2025 Kia Carnival, Corrie. There isn't a plug an play option for the hybrid models, but we do have the Curt Powered Tail Light Converter # C59236 that can be used. Would you like to have a return label sent out for the incorrect wiring harness? I can get that moving if so.
It was not the right part I sent it back on ups and it in Jacksonville fl as of now the tracking number is
1Z5DLT290309632020 so this will be delivered back to you as well
My refund will take some time that is two of them I sent back
etrailer was excellent to work with. I had to have a harness switched out because manufacturer switched plug ends at some point. Madison understood my issues and made sure I received the correct Curt harness. The Curt harness was perfect and the instructions were very clear and easy to understand. I highly recommend both companies and suggest talking with Madison but I’m confident that anyone you speak to at etrailer will be able to help you.
This did not fit my taillight connectors. I did not have time enough to exchange them before i needed to tow so I ended up cutting the connectors off and splicing the wires. Works great. Too bad I didn't have time to exchange for the kit made for splicing wires and saved a little.
the harness was good.etrailer was poor
Plug and play. Zero issues
Thank you for helping me with my 2024 Kia Sorento X line SX Prestige. I was told by Curt Technicians that they would not have a harass for months after ordering a harness 56474 which shows pictures of plug like my Kia in advertising but when shipped were nothing like the pictures. I called Etrailer and was assured I would get what was picture C63RV. It was as described and it works, Easy plug in, no problems. I am also grateful for the videos on the website, very helpful to let me know what I was getting and tips on how to install.
ALL IS GOOD Thanks
This kit was exactly what I needed to get the job done. The only criticism I have is that the manufacturer should extend the length of the green taillight wire because it was very tight in my application. But nonetheless, the install was pretty straightforward and I got it completed in a few hours by myself.
It was the rough part for the car sent it back as well
Perfect fit plug and play for my 2025 Sorento xline
Fits perfectly on a 2024 sorento x-line Limited with led light Canadian vehicle
fit vechile and install video was very helpfull
So far works great needs longer wire for passenger side though
It’s a joke .. it has to be .. it’s five feet short don’t reach from one side of the tail lights to the other . Why would you sell this?

I am sorry to hear this Dan, we have many successful installations with this wiring. I would like to see what the issue is, can you please confirm your year, make, and model?
Be careful ordering this. It is not for SX trim models. I called and talked to a salesperson before I ordered this and was still sent the wrong product. I will now Pbly have to pay shipping to return.
