I gave this Curt wiring harness an excellent rating even though the initial one I received didn't work! That is because of the EXCELLENT customer service I received from Curt when I called. They offered to immediately send me a replacement at no charge, which arrived in two days. I put it in today and it's fine. Tomorrow I will call them as they asked me to and they will arrange with UPS to pick up the old one for analysis. How many companies do you know that would do this???? Most will tell you to pay to ship it back and when they receive the old one, they will send you a replacement in their own sweet time. Curt ranks #1 in my book for customer service and I would not consider buying from anyone else now! One thing to Sedona owners that isn't the fault of Curt. Don't think you're going to install this kit without a fish tape to rout the wires from inside the taillight area and down to the back of the bumper. It is IMPOSSIBLE without a tape or flexible wire. You also have to run a heavy gauge wire (supplied) from the engine compartment to the left tail light area to power the conversion box. Things are not as simple as in the old days of just spicing into existing wires. 74679

I ordered the Curt hitch and wiring kit for my 2012 (4 cyl.) Kia Sorento. Mounting to the car went smoothly and wasn’t difficult thanks in part to watching the videos. I had a friend help which was nice, especially putting the hitch up in place. The products did just what they claimed to do and were cheaper than that other big orange and white place. I like how well Curt hides most of the hitch from view. A special treat was getting up graded to priority shipping (without my request) and receiving everything in about 2 ½ days. Win/win! 121334

The wiring harness was easy to attach. Everything I needed to get the 4-Way flat wire connector in place was included. I have ordered another wiring kit that will allow me to convert to 7-way RV connector with an electric brake controller. I'll soon be ready to tow my Aliner Sport pop-up trailer. 74508

This product is amazing. I recently had trailer wiring installed by Uhaul, and it did not work properly. Even though I purchased the 2yr wiring plan I decided against driving the 45 minutes to have them try and fix it for hours. I purchased this product and had it installed, tested, and completed in about 30 minutes. Everything works great. 97799

Everything worked great. Used a 4' long fiberglass rod to push up From the bottoming thru the left taillight attached the wiring of the rt taillight and pulled thru the small hole. Then passed the free end of pole up thru the right taillight and the hard part was done. Thank u Dana 71899

This product was fairly easy to install and worked like a charm the first time. The hardest part was running the wire from the converter to the battery. I actually ran it from the battery to the converter because it was easier to drop the wire down through a gap behind the engine. 89327

It definately had to be connected to the battery which was a pain having to run the wires to the front of the car from the back of the car. I thought it was just as simple as plugging it into the connector in the tail light. 100734

This product was fairly easy to install. The hardest part is routing the power wire from the taillights to the battery. The part takes about 20 minutes if the car isn't on a lift. Otherwise no problems! 133615

  • How to Determine if a 2013 Kia Sorento has a Factory Towing Prep Package
  • The most definitive way to determine if your 2013 Kia Sorento has the factory towing prep package is to have the dealer run the VIN number. They will be able to you how it is equipped. The trailer wiring for vehicles with the tow prep package, # 118541, is located behind the driver side rear wheel along the frame rail. I have linked instructions for you. If you have a 4 cylinder model or a model without the tow prep package use # C56163. For a trailer hitch, the most popular option...

  • Trailer Wiring Harness Recommendation for a 2012 Kia Sorento V6
  • The only wiring harness for a 2012 Kia Sorento that does not require a direct connection to the battery is # 118541, but it only fits models that have the factory tow package. If the vehicle does not have the factory tow package, you will need to use Tow Ready Wiring Harness, # 118506 or CURT Wiring Harness, # C56163. With either of these harnesses, a few customers found the green wire (for the passenger side tail light) to be a little short. One customer did find an alternate route...

  • Draw-Tite Versus Hidden Hitch for 2012 Kia Sorento
  • You hit the nail on the head. Hidden Hitch and Draw-Tite are manufactured by the same company, Cequent Performance Products. Both hitches are identical except for the label. Keep in mind that the hitches will not fit a dual exhaust vehicle (with pipes on both sides of the vehicle). If you are interested in a hitch with a less obtrusive appearance, the Curt Class III, part # C13073 might be a better alternative. I have edited a photo for you showing a rear view of both hitches once they...

  • Where Does Trailer Wiring Harness C56163 Install on a 2013 Kia Sorento without Factory Tow Package

This is just to ensure we can get you the correct option. Wiring harness # C56163 will fit base, EX, LX, SX models with 4 or 6 cylinder as long as they do not have the tow package. The connectors on the harness are designed to plug in line with the tail light wiring on the vehicle. I have included a link to the installation...

Factory tow package wiring requires certain components that are not present in vehicles without the tow package.

  • Trailer Wiring Harness Recommendation for a 2012 Kia Sorento
  • The main difference between the Curt Modulite Wiring Harness, # 56146KIT, and the Curt T-Connector Wiring Harness, # C56163, is that the T-Connector harness, # C56163, simply plugs into the factory tail light connectors at the back of the tail light assemblies. The Modulite Harness, # 56146KIT, will need to be hardwired into your vehicles tail light circuits. I would recommend using the T-Connector Harness # C56163 because you will not need to cut or splice into your vehicles tail light...

  • What is the Correct Trailer Wiring harness for a 2012 Kia Sorento 4 Cylinder

It will only fit the V6, towing prep models. If you have a 4 cylinder model, you would need to use # C56163. I have included links to the installation instructions for both kits for you.

  • Trailer Hitch and Wiring for a 2012 Kia Sorento LX
  • What is interesting about vehicles that can be pre-wired from the factory for trailer wiring is that the wiring might be there but you will not know if it is live or not. You will need to test the connectors in your picture using a circuit tester like # 3808. You will need to have someone sit in the vehicle and run through the functions while you test the connector. If it is a live connector then you can use the appropriate harness for a 2012 Sorento with factory tow package. Or you...

  • Pilot Brake and Tail Light Hitch Cover # CR-007A Will Not Turn Off
  • If the Pilot Brake and Tail Light Hitch Cover, # CR-007A, never goes out, then it is constantly receiving power from one of the tail light circuits coming from the vehicle. To begin troubleshooting, make sure your vehicle is turned off and the vehicle lights are off. If the hitch light stays on with the vehicle off and lights off, there is a problem. I recommend using a circuit tester, like our Quickee Tester, # 3808, to test each of the pins on the 4-way connector on your Sorento with...

  • Troubleshooting Trailer Running Lights on a 2011 Kia Sedona
  • It sounds like the problem is on the trailer side of the wiring equation since your running lights seem to work on your boat trailer, but to be sure you should test the running light of the 4-way with a circuit tester like our part # 3808. Check out the video I attached that shows how to do this. Its pretty easy, you would basically just need to turn on the running lights of your 2011 Kia Sedona and then test the pin on your 4-way that has a brown wire run to it for voltage. If its there...

  • Yes. This is a common issue with the Curt powered trailer wiring harnesses. There will be power to the 4-Way but it should not be enough to light up the trailer lights unless they are LED lights. If you plug in the trailer and the lights do light up then there could actually be a short somewhere. Use a circuit tester like # 3808 to test the wires leading into the converter box. If the signals are correct going in but not correct at the 4-Way AND the trailer lights come on when plugged...

  • Recommended Towing Package For 2011 Kia Sorento 4 Cylinder
  • If your 2011 Kia Sorento does not have the dual exhaust system with a tailpipe on both the driver and passenger side, I recommend the Draw-Tite Class ll Hitch, part # 36511. This hitch has a 1-1/4 inch receiver opening. I have attached an installation video for this hitch on a Sorento you can check out. You may be interested in a Draw-Tite Ball Mount like part # 36051. This drawbar provides a 5/8 inch rise or a 1-1/4 inch drop and measures 7 inches from the center of the hitch pin hole...

  • Trailer Running Lights Not Working when Coupled to a 2013 Kia Sorento
  • To me it sounds like the converter is working fine and the issue is with the trailer wiring. Since you tested the vehicle side connector and it worked fine that just leaves the trailer. And since you mentioned that the ground was causing some problems during a test, I think that is the exact problem, a bad ground. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. Since it has been a while since you have used the trailer connector,...

If the signals are not correct coming in then there is a problem with the vehicle wiring that needs to be addressed. If the signals are correct going in, move on to testing the 4-Way on the vehicle with the circuit tester. If the signals...
