Wiring a trailer can be a headache when you have to cut and splice wires, but this Curt T-Connector skips all that. The harness plugs in line with the tail light connectors, so there’s no need to tap into any circuits. Just plug it in and it’s ready for a 4-flat connection that handles running, turn, and brake lights.
The integrated converter keeps your trailer lights working right by matching the vehicle’s wiring signals to standard trailer wiring. It’s rated for up to 2.1 amps per side for stop and turn lights and 4 amps total for running lights, giving solid power without overloading the system.
Even if your vehicle didn’t come with a tow package, this harness makes it easy to add trailer lighting. It’s designed to work independently of factory tow wiring, giving you everything needed for standard trailer light functions without extra adapters or complicated rewiring.
Good grounding is key for dependable signal lights, and this harness is built with that in mind. The ground strap connects to bare metal for a clean contact, preventing flickering or intermittent light problems that can happen with weak grounds or corroded connections.

Delivered quickly and worked as promised. I found a video for the install and would recommend providing links with your product information for those who lack the experience to associate car model to the procedure. (I used a different car make and model to view the installation process because my specific car was not demonstrated)
Easy instsall, Not being familiar with body shop experience, had an issue with wiring and removing panels to get too the wiring harness too connect too, but got through that with a little extra time.
The instructions were easy to follow. Excellent product if you need a plug for a trailer. We have been able to pull a utility trailer with our car since I no longer have a pick-up.
Enclosed Instructions somewhat vague however when I viewed the etrailer video the installation took less than 15 minutes.
Good product. Prompt shipping. Highly recommend etrailer for all you trailer needs.
Great service, installed harness in 10 minutes perfect fit!
Besides usps delivering it 2 days late.
Check to see if your vehicle came equipped with a factory tow package before you order this. My 2010 4 cyl Santa Fe had the tow package and I didn't know or expect that it would. Tow package has a transmission cooler and a dedicated harness connection behind LR fender well.
The hitch and wiring I ordered were a exactly what I needed. Your website was easy to work through as far as getting the right product needed and everything installed just as easy. Delivery was also within a reasonable time. Will order from etrailer.com again.
Great product!

Wiring harness went in very well. I don't like the fact that I have to hang the wires and connector over the trunk to use it but this is mostly a car design issue. Good product.
I have not installed yet. However, delivery was good. Everything was in the box as ordered. It appears that all parts needed for installation have been included. Instructions appear to be very easy and understandable (color photos). Videos on website are a life saver. Wonderful Experience. Great website for information, prices, and installation and ease of ordering. Existing picture on site reflects package.

I mentioned this on my review for the Santa Fe draw tite hitch. These are the best value for the money. Installs in less than 10 min and it never causes issues with the light system and doesn't cause any permanent damage to the wiring if you choose to revert back to stock and sell the vehicle without any problems! Well worth the money!
On year follow-up. Everything still working fine. As I said in my previous post, during the last year I have pulled a number of trailers without problems and the lighting package has worked flawlessly.
Had one of these installed along with a hitch. Worked great until a tail light wire came loose and shorted against the frame. Reinstalled the wire in the tail light and replace the fuse. The tail lights worked, but the turn and brake did not. Checked the output of the module and there was only voltage for the tail lights. Ordered a new module wiring assembly and it arrived 4 days before expected delivery date. Installed it yesterday and it was really easy. The supplied instructions are simple and easy to follow. Watch the installation video before starting or if you have any problems. A flat blade and number 2 phillips screwdrivers minimum are necessary to get the job done.
Installation and quality is a 5 star. The only reason for the 4 star, which I struggle to give, is the wire harness must hang out the back door/trunk. The only bonus to that is, your harness does not corrode from the elements, but still slightly annoying to have it hanging out like a shirt tag.
I orderd a receiver hitch for my 2012 Sante Fe along with the wiring harness. The price was better than I found anywhere else and the hitch and harness arrived on time just as promised. Kourtney, the sales rep., was very helpful as well as very knowledgeable. She even sent me a link to learn more about the proper drawbar that I needed. Overall, it was a great experience and I highly recommend etrailer.
This is the second Curt wiring harness I've purchased. The first was for a 2014 Nissan Altima. This one is for a 2011 Hyundai Santa Fe. These harnesses are so easy to install with the connectors. I have mine leading into my rear trunk box. Installation is around a half hour. No issues over the past year.
I have had my trailer hitch and wiring on my 2012 Hyundai Santa Fe and could not be happier. It works great, and came with excellent instructions to install both the hitch and the wiring. The wiring was pretty much plug and play and the entire install took less than 90 minutes which included retapping the holes for the bolts. Would definitely purchase again from e-trailer!
I was very pleased with the electrical wiring for my 2010 Hyundai Santa Fe. It was very easy to install just followed the youtube video and it was a breeze. I feel relieved knowing that I didn't have to nip and cut any wires on my own. It was very secure and safe to install. One suggestion I would make would be to give the metal a cook sanding nothing to drastic, it works like a charm. I included a picture hopefully it helps out. I would definitely recommend getting this product.

Still going strong and have not had any issues at all.
purchased a couple of weeks ago, and between the video and paper instructions, the installation was a breeze. total time start to finish was about 30 mins, and everything works perfect!
Hassle free with etrailers equipment.
I'm a happy camper!

After one year, wiring harness is fine! Still works perfect
I have to rate this as excellent at this time of installation. Everything was great with the wiring harness and the fittings were nice and tight and the connections were solid and true. How this will hold up over the long haul we will see.

The harness does not seem to be functioning correctly. I am having a problem with one of the tail lights on the trailer it will not light. I checked the ground and used the tester at the harness plug to be sure it was not the trailer and it is definitely the wiring on the car and it is the harness since there is no issue with the tail light on the car.

I purchased the Curt T-connector harness for our 2012 Hyundai Sante Fe. It arrived with the Curt hitch I ordered in excellent condition in a few days.
The wiring harness installed very easy and it is easily well hidden inside the vehicle when not in use (keeping it all clean and servicable).
The instructions are easy to follow but they are a little to general. there are numerous plastic fasteners keeping panels together that can be overlooked and cause cracking of interior panels. extreme care should be used when disconnecting panels from one another or removing them from the vehicle. I fished my wires but the printed directions say you should remove panels....risky.
All in all these products from Curt are very impressive and I'm glad these were my decision.

You have to open some space to do the job neatly, but it isnt hard as long as you move slowly and dont force anything. I store the connection in the left side of the floor box, and lay it out under the hatch to the tow hitch when I need it. The weather strip is flexible enough to seal around it with the hatch closed. Look the job over first and only open up what you must. Its scarier than it really is. Good luck, make it fun
So simple to install and works flawless ly
I consider myself an advanced electrician/mechanic but those skills were not necessary . Product installed very easily as per the instructions and video clips I found on their website . Works as designed...excellent product . 2011 Santa Fe . 6 cyl W/O factory tow package .
Perfect fit for my 2009 Hyundai Santa Fe GLS w/ FWD. I had the hitch assembly installed at the trailer rental place. They wanted me to buy their wiring harness that they would have to cut and splice to my wiring in the rear. I instead bought this as a much better option that plugs right into my taillight assembly. Easy self-installation. I would definitely buy again and highly recommend it.
