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 interior trim panel in your rear cargo area. 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.

I ordered this harness not knowing if it would work on my 2021 Kia Sorento ex+. Turned out to be a perfect fit. After going on multiple forums to find the tow package, I finally found the male end fastened to the top side of the metal plate under the cover as seen in pictures. So what I am saying is there is no question this harness fits the 2021 Kia Sorento.

Easy to install and adapt to existing wiring in the 2022 Hyundai Palisade. I also purchased a 7 pole adaptor and it turns out that the Palisade had factory standard wiring run to the rear(on the Calligraphy Edition) to accomodate it as well without having to run new wire to the engine compartment and brake controller.


Hitch and harness arrived when expected, complete with all hardware needed. Installation was straightforward. Would definitely recommend etrailer.


Wire harness 'should' be easy, but things never are. Except this time! Got the correct harness, and it was plug and play! EXCELLENT!


Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
Works great, easy install


Great product, great company! The trailer hitch and wiring harness are barely visible and significantly less expensive than the dealer. Highly recommend!


I had to customize the plastic splash guard on the undercarriage slightly to fit it back into place after installation of the wires. Other than that it was very easy to install. The adhesive that came with the connector was no longer sticky so I used tape to hold it in place until I could replace the trim.
Works great!


Wiring harness was easy to install, just plug and play.


E-Trailer Rocks, I was very thankful to receive great customer service from their knowledgable staff. Stoked to get this installed and working properly.


Could not have been easier to install. Only issue was that the double sided tape had lost it's adhesiveness. Had to use my own double sided tape I had on hand.


The kit was easy to understand and I had no problems with the installation.
Exactly as advertised.


I watched the video prior to ordering, and it was excellent. When my hitch and wiring harness came it all went on super easily. Thirty minutes from start to finish, everything fit perfectly, and the installation is fantastic. I think it looks better than the OEM option, since the frame is all hidden and the only visible thing is the receiver itself. Bonus points for the free shipping and quick delivery.


Very easy install due to the detailed instructions from etrailer.


Works perfect apparently better than factory(all factory Palasades recalled due to the factory part sold at Hyundai dealers),no issues after 20,000 Miles and the hitch is awesome also!


Not a bad product overall but external electrical connections like this should contain a small tube of protective lubricant or be pre lubed. With this you need your own.

You are right. It is recommended to use a bit of dielectric grease like item # 11755
Dielectric Grease for Electrical Connectors, 2 oz.
to protect your connections.

After about 1 1/2 year the hardness doesn't work for the the left turned signals .I tried checking everything & it's the hardness

There could be a few reasons as to why the left turned signal is not working. It could be that the wire connectors where they plugged into the vehicle connectors have become loose. Or it could be that the ground wire connection is loose or needs to be redone. I have a FAQ listed below that can help.

Installed on a 2020 Sante Fe SEL in my garage, did not lift the vehicle, so a little tight. I also wired for trailer lights and that too was simple. Looks good, should work perfectly. Will be using to pull utility trailer, bike rack, and carrier. Harness was easy to install, used zip ties to secure to vehicle. Completely out of sight.


This product installed easily, and I highly recommend getting a harness with a fuse! Quality product the online ordering was easy.

2020 Hyundai Palisade

This is the second etrailer hitch and wiring harness I’ve installed and it was simple to do. From the ordering process through their easy to use website to their installation videos it had been a great experience and I recommend them whenever someone asks me about getting a hitch for their vehicle.


Plug and play!

2021 Hyundai Palisade

Perfect fit for wiring harness. Easy to install and came with enough zip ties to hang the wiring properly. Only minor down side was that the double-sided tape had dried out, no big deal.

I recommend using your own double sided tape to make sure that the harness stays in place.
-- Etrailer Expert Jenny N - 12/21/2021


I had very good service and help me with any questions I needed answer and the people I talk to were very pleasant I will do business with them again when the time comes


Worked perfectly. Easy installation


Straight forward installation and worked with no issues.


love my hitch and wiring from etrailer
