Installation
This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, on the driver's side. Once you've plugged in the T-connector, insert the included 10-amp fuse into the integrated fuse holder.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
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.

Video of Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Speaker 1: Today we're going to be taking at look at the Curt T-connector vehicle wiring harness with a four pole flat trailer connector. This product fits certain years and models of the Kia Sedona, Kia Sorrento, Hyundai Santa Fe and Hyundai Veracruz. To ensure that this is the fit for your vehicle you can always use the vehicle fit guide at etrailer.com.This provides a four way flat connector at the back of your vehicle to power your trailer signal lights. This is designed for use with vehicles that have a factory tow package. It is compatible with five pole, six pole and seven pole adapters, adapters are sold separately and it comes with a dust cap for the four way flat connector that way you can cover up the connection points when your plug's not being used. That dust cap is tethered to the actual plug housing so you don't have to worry about misplacing or losing that cover.The black box on the unit is the included taillight converter.
This ensures that your vehicle's wiring matches that of your trailer's. The power module connects directly to the vehicle battery through the wiring to avoid overloading your vehicle's electrical system. That unit's constructed using surface spot technology. It's going to offer consistent reliable performance. What that does it it maximizes the trailer light yield and intensity while producing minimal heat.
Also ensure superior operation, even in rough road conditions.This is designed to connect quickly and easily. You'll notice how a lot of the wiring's protected with a nice wire loom material. It's going to keep your wires together and safe from harm. So basically what you do when you're ready to connect it, locate the connection points behind the rear bumper and plug in your connectors. These connectors are custom fit for the the vehicles that I mentioned earlier so they're going to match up perfectly with the ports on the vehicle and they're going to snap lock together for a nice tight secure fit.Once you have those plugged in you'll need to mount your convertor box to a safe out of the way location.
You can do that using the double sided adhesive tape provided with the kit. And then you will need to install the included 10 amp fuse directly in the fuse holder right here. So it slides in there and it's got the cap that comes over to keep it safe and protected.Once you have that done you can secure any excess or slack in your wiring with the included cable ties. And once the installation's complete, the four way connector's going to be stowed beneath the vehicle near the trailer hitch. We do recommend using a mounting bracket to keep the connector secure and easily accessible.
Mounting brackets are sold separately and available at etrailer.com. We also recommend that you use a small amount dielectric grease in all your electrical connections like the plugs on the vehicle and the four pole connector itself. That grease is specifically designed to help prevent corrosion of the connection points. It's sold separately as well and available at etrailer.com.When it comes to maximum amperage for the stop and turn lights we're looking at 3 amps per circuit. For the taillights we're looking at 6 amps per circuit. The unit also comes with detailed insulation and instructions to help walk you through the whole process step by step.That's going to do it for today's look at the Curt T-connector vehicle wiring harness with the four pole flat trailer connector.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs into OEM tow package wiring harness. Powered converter reduces strain on wiring system. SMT construction ensures superior performance.I haven't yet installed or used the product, but I'm highly impressed with the customer support and the video that lead to me buying this product. I look forward to using this to tow a pop up trailer. 643055
Quick and reasonably priced shipping, accurate order filling, competitive pricing, and phone access with NO wait when I had a question for etrailer! Very refreshing. Plenty of helpful installation videos on line really helped. Would have been a quick and easy installation except for the Curt 2 sided tape meant to hold the converter box to the car. It held for all of 10 minutes despite cleaning the surfaces and holding strong pressure on it. Surprisingly, it stuck to the car but not the box. The included self tapping screw didn’t work either so I used a sheet metal screw into the thick plastic to hold the box on. Plenty of zip ties included. End result-works perfectly with 2 simple plug ins to my Sorento factory wiring. 682020
Great product, high quality and finishing. It was easy to install especially with their installation videos. 545291
I tried to use trailers a few times, the lights were not working. 665527
The first step in any trailer lamp troubleshooting process is to determine if the problem lies with the vehicle wiring or in the wiring on the trailer itself. The easiest way to do this is to try a different trailer on the vehicle and a different vehicle with the trailer in question. If a different trailer or vehicle isnt available, youll need to use a circuit tester like # 40376
Circuit Tester Kit
$61.02 and test the pins on the trailer connector as a helper activates each lighting circuit. If the trailer connector isnt activating the tester, first ensure that the inline 10A fuse is in place, then make sure all necessary fuses are in place in the vehicles fuse box. Also make sure that the harness is fully seated into the tow package connector on the vehicle. Ill also link you to a help article that will assist in the troubleshooting process.
Mike L - 07/03/2019Bought the Curt Hitch and harness, Great product, great price, easy to install especially with their videos, fit great, fast shipping. 4 prong connector cable on wire harness could have been about 3 inches longer for my application as I mounted the module under the side cover as per video. Would have liked a mounting bracket on the hitch itself for the 4 prong trailer connection bracket. Came one day earlier than expected, but ups must have handled it pretty rough as the two outer ends of the hitch had punched holes through the box and scraped the ends. etrailer was great, will buy again and recommend. 498326
Works great, looks great
Gary - 04/19/2019Installs easily with plug-in connections. No need to run a separate power 12v power line or make any splices. Wish the four wires from the controller to the four-prong flat connector had been about a foot longer. That would have allowed me to place the controller in an area that is more protected from corrosive road moisture. Industrial-grade, adhesive-backed Velcro patches provide a more reliable means for attaching the controller to a clean flat surface than the adhesive patch provided in the kit. 499524
Hitch fits great and the wiring kit was easy to install. I simply unhooked the rubber exhaust hangar from the end of the tailpipe and the two nuts which fastened it to the back of the muffler. That way, I could easily remove the tailpipe for clearance to the passenger side hitch bolts. 462940
Easy install. I was surprised to see Hyundai provided a plastic cover to protect the wiring for the trailer, a definite A+ in my book. My only issue is that I wish the Cable from the module was long enough to keep it covered in the same area with the Hyundai trailer connectors to also keep it clean and dry 436744
This has been a great addition to my Santa Fe. Shortly after installing this hitch, we helped move a homeless family to West Virginia from the Hampton Roads area with a [rental] trailer. It has come in handy with our new trailer and some of the yard work and projects weve had.
Joe C - 09/27/2018Shipping was slower than I thought it would be. When it came everything was there and it fit like a glove. Video's were essential for selling the product. And it went on just as easy as watching the video. Thanks 492105
Was not able to install the wiring harness to the vehicle
Delynn F - 04/02/2019easy install and works great! Perfect fit 728676
This wiring harness was exactly what we needed. It fit perfectly on our Kia Sorento (for which it was designed). Easy instructions, electrical attachments were well designed and easy to push into existing assembly on the Sorento. Electrical wiring on a car doesn't get any easier than what is offered with this product! 726799
This was plug and play on my vehicle. The only thing that would be nice is if it were able to attach to the hitch 726550
Very easy to install on a 2019 Kia Sorento with the factory tow package. It plugs right into the factory connectors. For the 4 Pole Flat connector I used bracket 18144 since the wire is fairly short. It looks clean and professional. This bracket attaches directly to the no-drill bracket already present on Draw-Tite hitch receivers. To check if your vehicle has the tow package you just need to pop out the 2 plastic rivets on the driver side panel shown in the install video and see if the 2 connectors are present. I was not able to confirm through the dealer or Kia corporate which Sorentos have the factory tow package. 725074
Simple install. Works as advertised. 723077
Instructions were great and this was easy to install on my 2017 Kia Sorento. 722544
Plug it in, zip tie the wiring for safety and hit the road. Couldn't be simpler! 720909
Very prompt with friendly agents, especially Beverly. 719728
Everything was good with the product, but I got the wrong number of nuts for the installation and had to make a trip to the hardware store. 719709
Easy to install 719441
Fast delivery and clear installation instructions. Installed myself but two people would make it an easier install. 717464
The harness was easy to install and works well. 717135

Works perfect. Quick to install! I would recommend! 714802
Great service and product fit as descri bed. 714690
Received product quickly, hopefully it installs as easy? 713325
was easy enough to install with the factory tow kit on my 17 Hyundai santa fe. Instruction pictures and installation video show ground (White) wire is connected to one of the electrical connectors. This was not the case as mine came with the white wire hanging loose, easy enough to install a ground connection to the frame as I did not know how to open the electrical connectors to attach the ground to the actual plug. 711806
Everything was as promised easy install and all parts fit properly!! Great product I tow a 23’ boat behind a Kia Sorrento no problem!! [Thumbs up] 711078
Fast service for the trailer hitch wiring harness for my 2019 KIA Sedona. 711037

Well made products, easy to install, saved a ton of money. Very pleased overall. 707181
Exelent product fits right on very easy to install 703322
This was the first item I have ever purchased from etrailer.com. The item arrived in good condition and was ready to be installed on my KIA 2015 Sorento. The wiring kit replaced a wiring kit that was damaged when someone ran into the rear end of the KIA. To complete the installation, all I had to do was remove the existing wiring kit and install the new kit. Total time to install took about 20 minutes. The kit was complete, although some of the smaller parts I did not use as I reused some of the parts from the existing kit. Everything fit perfectly. 697351
Just what i expected and a perfect fit. Came very quickly and was oem quality. 699162
Works great! Have had it over a year with no issues at all. Highly recommend. 695666
I've had this on for 1 year and it works great, it was the lowest price I could find! I've only used it a few times but it does the job and saved over $100 on parts from what the installer would have charged. 697000
Excellent products and service. Very easy website to use. I bought a trailer hitch, wiring system, and a few other things needed for the job to be done correctly. Everything fit as promised! Videos were accurate and extremely helpful. Usually things are never as advertised . . . things were even better than advertised with etrailer! I will use again and tell everyone I know! 693130
Perfect fit and spot on detailed intruc tions. 690875
This is the third hitch I have purchased from etrailer. Was easy to install and is of good quality. 687049
Still Very Happy with the trailer hitch I purchased a year ago. Functional. It was easy to install and using the installation pictures as a guide on the internet it was definitely a plus. 686750
I got the parts in a timely fashion. 683412
Installed simple and easy with the hardware and instructions provided. Seems to be nice and heavy-duty. Thank you for the fast and free shipping with this item as well. 688145
Can you say plug and play.....well in this case it was plug it in and light em up. My Sante Fe Sport was prewired and the harness that I purchased from y'all matched up perfectly..... it's been 1 year and I have had ZERO issues. Installation for this item was about 45 minutes. So.....in less than 2 hours I had installed my receiver hitch and the wiring harness (by myself in the driveway). Thanks again for a good product at a really good price. My apologies for not having any pics.... 681894
Product well made. Only complaint is that the four prong connection wiring very short. 681681
Easy to install. Just as advertised. 680475
Right product for the job fit my vehicle perfect. Great video on how to install it. [Anybody] could do it 681257
Great product and fast service, thank y ou! 677122
Ordered this item along with a full trailer hitch assembly. Draw-Tite hitch, Ball Mount, Curt Wiring Harness. All was delivered in a timely manner and works great. Super easy to install and the corresponding install video's were very accurate. 674438
Easiest installation I've ever done, mostly due to the vehicle manufacturer’s foresight. 674062
