Tow Ready Custom Fit Vehicle Wiring - 118506

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.


  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn lights: 4.2 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


This custom-fit T-One 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.

T-One Connection Location Points Behind Tail Lights

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 and insert the provided fuse.

Once installation is complete, the 4-way flat 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.

ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. 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 your trailer. This power module functions as a tail light converter to combine 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.

With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Video Transcript for Trailer Wiring Harness Installation - 2011 Kia Sorento

Today, on a 2011 Kia Sorento, were going to install part number 118506 from inaudible. First thing well do is were going to remove the two tail lights. Well remove two screws here and here. To disconnect the harness, first inaudible the right here, and pull the part. Well put those aside and repeat the same process over on the passengers side. The next thing well do is remove this plastic ring right here.

That fastener will not be reused. Well take the wire harness dropped between the body work and the body. That will be the same thing with our T-connector with the red wire. Alright. Next, were going to go ahead and test our black wire that come from the kit to our red wire here and this eventually get run to the front of the vehicle to the battery.

Then well take the black wire and do the same thing with other wires. Well inaudible through here and pull the wires down. inaudible and test the module. The module has a bracket with a threaded hole in the end and inaudible hardware into it inaudible main fasteners that allows to cool and to face you back a little bit more so you can run the module underneath. Well put the two fasteners back in, now Ill take the white wire inaudible terminal and inaudible to the body.

Now well take the wire harness, plug it into the factory wire harness, snap it together and then well go ahead and install the inaudible.Then well take the wire harness and well run it behind the support for the bumper cover then down to our hitch. With the red and green wire, were actually going to run it above the bumper bracket over to this wire thats a little bit on the short side. Then were going to run a piece of tubing and well use that to help pull the wire over the bumper bracket. Then well run it the same way to the passengers side. So when you run the wire direct to rout as possible because theres very little leftover.

Theyre going to be attached to the wire harness thats attached to the tail light. Now were going to run the black wire and roll it up to the front of the car and to the battery. Make sure it stays away from anything thats moving or anything that gets hot like the exhaust. And when you run it to the engine compartment, the same thing applies as you run it to the battery. Well run the wire to the inaudible side of the battery well be attaching it to this terminal here so well cut our wire short .

Prroduct arrived within a week. The installation videos were a tremendous help. I installed the hitch myself and use 2 hydraulic bottle jacks to raise the hitch, which is quite heavy, into position until I was able to thread a bolt in on each end. After getting the unit suspended on 2 bolts, I was able to center the hitch side to side, install the last 2 bolts and use the jacks to raise the hitch firmly to the car frame so I could snug the boltsup. I used a short piece of 2x4 to wedge between the muffler and auto frame to give room to get a socket wrench on the last bolt to tighten it. The muffler only needed to be shoved out of the way slightly. No need to remove ot from its hangers. It would be easier to install with a helper but not difficult by myself. No need to cut bumper. Wiring was a challeng only because of difficulty of getting it threaded up the passenger side fender. You need a skinny flexible length of whatever u have to push down thru the fender till it exits below. Then tape your wire harness to it and wrestle it up to the light. I chose to route the power cable thru the car interior and that was a chore. Easier to route under car but more exposed to elements and damage. I found one wire under the dash that penetrated the firewall and was able to punch the power line thru its rubber boot seal with an awl that got the power cable into the engine compartment. The connection to the batter was easy. I recommend this hitch for the DIYer. 75443

A year ago we purchased a hitch from etrailer, and also a curt wiring harness. After the curt harness failed, and etrailer sent me another one which ultimately failed (both times the right brake signal light stuck on, and would wigwag flash against the left when the left signal was used), I decided that maybe a different brand harness would be a wiser choice, but winter came and I didn't need it as we'd missed the camping season. I recently ordered this T-One unit, and found it to be much bulkier than the curt unit, but the circuit was split differently, and it felt all around much sturdier. It works great, and I look forward to hopefully getting many years of use out of it. It will be nice being able to go camping this year as a family. So looking forward to it, and the service that etrailer has provided has been second to none as always, and if you own a Kia Sorento, I would recommend the T-One unit. 133770

Perfect fit! I just installed today and working so far. I say that because I had installed a curt harness and only lasted a month. Unfortunately I purchased it on ebay and didn't bother trying to contact them. I'm trusting you that if I have problems I can call. Thanks for quick delivery!! 40980


I had the same problem with the Curt harness. The first one was messed up the second day on the job, and now the second one is bad two months down the line, and I havent even had the trailer connected to it. Im taking the trailer across country in two weeks. Im going to junk the the Curt module, and buy this one. E-trailer has been great, they sent the replacement right away after the first, but Ive had enough, no more Curt products for me. Im not going to try for a 3rd strike. Especially when I know the problem isnt a result of the trailer. The curt modules just dont do it, and even despite the excellent service from E-trailer, I really dont want to have to keep crawling under my Sorento to remove the box every six months!

The hitch installed in about half an hour on a hydraulic lift. There is a good inch between the hitch and the muffler. The wiring took over two hours hiding all the wires. It could be done in less than an hour if i had to do it again. 16060


what model hitch do you go with? what wiring kit did you use?

Received the wiring kit and installed it myself with ZERO automotive / mechanical experience whatsoever. The directions were simple and surely sufficient for anyone with experience, but for me, the youtube videos posted here on etrailer were invaluable and made it easy. Initially, running the black wire under the car and up to the engine compartment scared me. It seemed daunting, but I found that the existing wiring and transmission lines were situated right down the chassis underneath and had some places for additional wires so I was easily able to run the wire with the existing wire and transmission lines under the Sorento. Easy as pie. add a couple zip ties for safe measure and presto. Two hours later, everything is wired and looks great. Very professional. 177112

Item arrived in 4 days. All parts fit as advertised. Hardest part of installation was routing wires through the chasis, as there are some tight spots around the tail lights. While the installation video was helpful, I think some more video under the car for routing the wires would have been helpful. Installation took about two hours because of some trial and error. Overall it was not too hard of an installation. Dealer wanted $575 to install wiring and hitch on my 2012 Sorento. By installing myself, the cost was roughly $240 for the hitch and wiring assembly. The cost difference will pay for the utility trailer I have been looking to buy. Thanks etrailer for a good experience. 111359

This installation went mostly okay. Everything plugged into place as described. I agree with some other comments on this forum that if you follow the installation instructions exactly, there isn't enough wire to reach the passenger side lights. I ended up running mine right behind the bumper hugging the rear door seal. That made it work out just right. The real bear of the installation was running the power supply up to the battery. I had trouble with this and am not 100% satisfied that it looks professional. That one part took 70% of the time to install. 15070

Installation of hitch and full wiring harness went smoothly. No issues that others had mentioned, didn't have to drill out frame or cut away at center of bumper. Also, had plenty of wire, didn't have to splice any additional...trick was to hug the inside of bumper. Watching videos helped to simplify the installation, along with a little patience. Toughest part was to fish the wiring up through the passenger side tail light opening, bent coat hanger worked well. Would strongly recommend etrailer, price was reasonable and installation straightforward. 35562

by: Brian C05/24/2011

I did not have enough wire to connect to the passenger side tail light without more disassembly of my new vehicle than I really wanted to perform. l-added jumper inline with the wiring-potential ground point. Also, in order to allow more room for the installation I made up the butt connector for the battery positive wire before mounting the harness behind the driver's side tail light. Running to the battery was fine, not professional by any means but should work. Maybe some mounts and adhesive would help to make it more professional. Works as described. 15283

Received my hitch for my 2013 Kia Sorento in about three days after placing my order. Everything was there and in good shape. The delivery company did a job on the box but the merchandize was fine. Only question is the instructions for the $72.00 wiring harness were a little shy on instructions but I think I can figure them out. Would be nice to see more info in the installation of the wiring harness. Your employee Gail was very helpful and efficient and I will give your company a 9 our of 10. Keep up the good work. 98835

Great product, well made... videos are very helpful, as are the instructions. The only part I had a hard time with was pulling the fascia back to fit the converter box down inside. I actually pulled out the other two screws and yet didnt feel like enough room but did eventually drop in... lights work great Curt light harness is junk, buy this one... it works !!! 181205

This product installed perfectly and components all fit well, just as advertised. Being a novice, I followed a U-tube video or I may have had slight difficulty. All the lights check out perfectly.

The harness was simple in nature to install. The hardest part was fishing the wires behind the bumper and running the negative to the front of the truck. It took over an hour to do bc of tight spaces and trying to figure out where to run everything. I could probably cut 30 mins off if I had to do it again. 48852

by: Danny07/06/2011

Ordered for a 2011 kia sorento, overall easy install, but a bit time consuming. Control box was a tight squeeze to fit in the space and running a power line to the battery was a task. But in the end it makes for a very solid and clean install. Probably took about an hour and a half to run all the cables. 18596

This wiring harness is very well made with all corresponding wires bundled neatly together to avoid any confusion. The installation went exactly as demonstrated on the video which was VERY helpful for those of us who are visual learners. Once installed, it operates as advertised. 94915

The wiring that runs from the drivers side to the passenger side is short. There is an alternative path, but it is difficult to reach without small hands. I would suggest either making the wiring a little longer 5 inches? or more clearly showing the alternative path. 77036

by: Scott B.03/16/2014

Product was as advertised, and as they mention in the video, you do not have very much play went you string it over to the passenger side. Took me a few times till I got enough to hook up. Other than that, awesome product, great site and excellent customer service! 120891

by: Reese L.06/03/2012

Very easy to install once you figure out how to run the power to the battery. Other than that everything went well. I ended up following the brake lines from the rear to the under the hood area. Get a lot of zip ties to make sure everything stays snug. 42537

by: Scott W.03/31/2012

Tight fit behind the lighting assembly. Someone should note "exactly" where to route the wires as there are two choices down in the body panels. One leaves the wires too short, one is just right....... I routed wires twice.... no big deal. 35753

T-One connector The T connector works as described, but I found that the wiring harness for the passenger side lamp was too short. I had to add approximately 6" of wire to get it reach. Overall its a good kit and it does what it says. 4580

First, if the vehicle does not have a 4-Way trailer connector, you will need to add one using # 118506 if you have a 4 cylinder or other model WITHOUT the towing prep package. If you do have the towing prep package, use # 118269. I have linked instructions for both harnesses for...

  • The wiring harness for your 2011 Kia Sorento is the Curt Custom Fit Vehicle Wiring, # 118506, and it comes with the power wire. It is necessary to install the power wire because the converter requires power directly from the battery in order to distribute that power to the harness and protect your vehicles sensitive wiring. This harness can be used with an adapter for your 5-flat trailer connector. You will need the Adapter 4 Pole to 5 Pole Trailer Wiring Adapter, # 20036. The included...

  • In order to use the MaxxTow carrier, # MT70106, you will need a Class III trailer hitch with a 2 inch receiver. The most popular Class III hitch for your 2011 Kia Sorento is # 87574. I have included links to the instructions and a video showing a typical installation for you.

  • Trailer Brake and Turn Signals Do Not Work when Running Lights are On, 2011 Kia Sorento
  • It sounds like there is a ground issue that is causing the malfunction. First, you can do some tests on the vehicle side to see if it is the problem or if it is on the trailer. You will need a circuit tester like # 3808 if needed to test the wiring. Disconnect the trailer from the vehicle and use the circuit tester to test the wires that go into the converter from the vehicle. Using the circuit tester, have someone run through the brake, turn, and running light functions while you test...

  • Recommended Hitch and Trailer Wiring Harness for 2013 Kia Sorento SX
  • According to my research, the 6 cylinder models of the Sorento like your SX can tow up to 3500 lbs. I would recommend the Curt Class III hitch, part # C13073. If your Sorento was equipped with the factory tow package, you would use the # 118269 you referenced. If your vehicle does not have the factory tow package, then the connectors you located under the vehicle are most likely not active, and you would need to use # 118506, which would plug inline with the factory wiring harness feeding...

  • Trailer Hitch and Wiring for a 2011 Kia Sorento EX
  • For your 2011 Kia Sorento there are Class II and Class III trailer hitches available. I recommend Class III because they have a 2 inch receiver which will afford you more accessory options and they are more stout and have higher capacities. The Class III trailer hitch I recommend is # 87574. It s rated for 350 pounds tongue weight, 3,500 pounds gross trailer weight. It is also rated for use with weight distribution. I have linked a video showing installation of this hitch for you. If...

  • Differences Between Hitch Options and Recommendations for 2013 Kia Sorento
  • All the hitches available for your 2013 Sorento have the same 3500 lb towing/350 lb tongue weight capacity. Although they're designed a bit differently, in my opinion none of the hitches would have a strength or quality advantage over another. All the hitches, the Hidden Hitch # 87574, Draw-Tite # 75684 and the Curt # C13073 would be partially visible under the back bumper, but most feel that the round tube Curt # C13073 looks better. None of the hitches would be a fit for vehicles with...

  • Tips for Routing Trailer Wiring Harness Power Wire to Battery on a 2011 Kia SOrento
  • Wire loom is not necessary but it can be used to protect the wire. You can get a 10 foot long section # 7509-10. You would likely need more than 10 feet though. Routing the wire on any vehicle is a matter of preference. There are basically 3 ways to do it: under the vehicle exposed, under the vehicle not exposed or partially exposed, and through the vehicle interior. I have included a link to the right to a help article I wrote with tips on routing the power wire.

  • Trailer Wiring Harness for a 2012 Kia Sorento
  • Your 2012 Kia Sorento has a separate wiring system. This means that the brake lights and turn signals are on different circuits/bulbs. Trailers on the other hand have a combined system with the turn signals and brake lights on the same circuit/bulb. So you would not be able to just wire in a vehicle side 4-Way directly to the lights on the Sorento because you would either have brake lights or turn signals but not both. You will need the proper harness that includes a converter for...

  • Trailer Hitch Recommendation for a 2011 Kia Sorento
  • The easiest way to know for certain whether a vehicle has the tow package or not is to check with a Kia dealer with your VIN. With that info they will know all of the options your vehicle was built with. Typically the tow package will include a trailer hitch at the rear of the vehicle and a trailer wiring harness like a 4-way or a 7-way. It looks like you are looking for a trailer hitch for your 2011 Kia Sorento EX. The good news is that the Draw Tite hitch part # 75684 would be the...

  • Comparing Curt and Tow Ready Trailer Wiring Harnesses for a 2012 Kia Sorento

  • Will the T-One Wiring Harness Part 118269 Work with my 2011 Kia Sorento LX Base Model
  • Thanks for sending us some pictures! Yes, the T-One wiring harness # 118269 will work with your 2011 Kia Sorento LX V6 engine with the tow package. If you have the LX 4-cylinder engine without a towing package, then you will need the T-One wiring harness # 118506. Most base model Kia's won't come with a tow package so I would double-check to see how your vehicle is equipped. Since you are adding a wiring harness, I recommend using a small amount of dielectric grease like # 11755 to...
