• Troubleshooting Curt Weight Distribution that Makes Loud Scream Around Corners
• Weight distribution systems are prone to making some odd noises, but a sound that would wake that dead is probably on the higher than normal side of things. The lift brackets of the Curt kit part # C17500 that you referenced can be greased and you can grease the zerk fittings on the bar holders of the head but beyond that Curt does not recommend greasing any of the other moving parts as the friction there is part of the sway control. Best option is take all of the moving parts apart as...

• 7-Way Not Working Only When Plugged Into 2017 Kia Sorento
• I do have suggestions, and since you have already done a lot of the legwork here I think we can find the issue. Since you plugged your camper into another vehicle and it was working fine, and your 2017 Kia Sorento's test only came back as the electric brakes working, there are a couple of possible solutions. Though you said nothing looks to be blocking any of the prongs, I recommend first just starting off by taking as close a look at the blades as possible for any type of corrosion, which...

• Trailer Turn Signals Not Working After Installing Trailer Wiring Harness on 2008 Kia Sorento
• The Curtwiring harness # C56332 is designed to fit a 2008 Kia Sorento that came with the factory tow package. You can have the dealer run the VIN to determine if your Sorento was equipped with a factory tow package. If it was not then you would need to use a hard wire harness, # C59496. If it does have the factory tow package then there is most likely a bad ground causing the problem or, if the vehicle uses relays for its tow package wiring, a bad relay. Relays can be obtained from a Kia...

• Troubleshooting T-Connector Wiring Harness Installation On 2015 Kia Sorento
• When installing a T-connector like part # C56256 and getting no signal to some of the wiring, the problem is the ground. Make sure the ground is attached to a clean bare metal surface and then recheck the lights. You can make sure you are getting current to the trailer plug by using a circuit tester like part # PTW2993. Have someone sit in the driver seat of your Sorento and run through the functions while you test the pins. Make sure all of the connectors are securely attached and you...

• Trailer Running Lights Do Not Work for Trailer Towed by 2012 Kia Sorento
• If the 4-Way does not show power for the running lights then it could be the converter or it could be something with the vehicle. Consult the vehicle owners manual first to find the locations of the tow package wiring fuses or relays and check the ones related to the running lights. If blown, you should just have to replace with a new one and everything will work again. If everything is intact you will want to use your tester to test the wires going into the converter from the vehicle....

• Trailer Lights Not Working After Install Wiring Harness on a 2014 Kia Sorento
• To determine if the problem is with the vehicle or the trailer, first disconnect the trailer from the vehicle. Then use a circuit tester like # PTW2993 or the one that came with # C59496. Test the pins on the 4-Way using the circuit tester while someone sites in the vehicle and runs through the functions. If all the signals are correct on the 4-Way when you test it, then the issue is on the trailer. But if the signals are not correct then there is a problem with either the wiring harness,...

• Troubleshooting Popping Sound When Plugging Trailer Into Curt Echo Brake Controller
• I reached out to my contact at Curt regarding the issue you experienced when plugging the trailer into the Curt Echo # C51180. He said the popping sound along with the immediate shut down of the Echo indicates some kind of short, likely on the trailer side. From what you described the power wire has been installed correctly on your Sorento from the connector to the battery. I recommend first just inspecting the trailer side 7-Way to look for any debris or corrosion inside the pins that...

• Repairing Trailer Connector on Recently Purchased Pop-Up Camper
• To answer your question, you'll need to determine the function of those other two wires. If I had to guess, I'd say your pop-up most likely has a 6-way connector. One of the unknown wires is probably for trailer brakes and the other one is likely a 12-volt accessory power feed to the trailer, most likely used to maintain an on-board battery. The power feed doesn't have enough push to charge a dead battery, but it can provide enough power to keep a charged battery topped off. You'll need...

• Troubleshooting Trailer Wiring Left Turn/Stop Signal Not Functioning After Wiring Install
• Most likely the problem is that the connector that runs to the left turn signal of the vehicle just isn't fully seating so the connector does not have the voltage at the pin. However, you can test to make sure the problem isn't the converter box of the harness by using a circuit tester like part # PTW2993 to test to see if voltage is feeding into the box on the left turn/stop circuit. If voltage isn't there on the input side then the problem is in the connectors that attach to the taillights....

• Trailer Running Lights Stopped Working with 2015 Kia Sorento
• I will be happy to help figure out the problem with the wiring harness on your 2015 Kia Sorento. The first step is to determine where the problem is. To do this some testing is required using a circuit tester such as # PTW2993. Or if you have a meter that will work too. With the trailer disconnected you can test the wiring harness. First, check the brown wire that goes into the converter box from the vehicle. This is the running light circuit. If it does not show power with the vehicle...

• Troubleshooting Running Lights Turning On When 2011 Kia Sorento Lights are Off and Vice Versa
• I spoke with my contact at Curt, manufacturer of the # C59236 wiring harness for the 2011 Kia Sorento. He stated that he has not heard of this problem, but there is a test you can perform to help narrow down the problem. You will need a circuit tester, like part # PTW2993. First, test that brown wire going into the converter for the proper signal. If you find that this signal is incorrect (provides power when the lights are off and vice versa), then there is most likely a wiring problem...

• Troubleshooting Utility Trailer Lighting Signals After Winter Storage
• The first thing to check on your trailer is the main ground wire. After winter storage it is possible the trailer's main grounding point has corroded. A weak ground can cause all sorts of weird behavior from trailer lights. Remove the ground ring terminal and sand the grounding point to remove all rust, grease, dirt, paint and primer to expose clean bare metal. Re-attach the ground wire ring terminal and apply dielectric grease # 11755 to block water and dirt. Since the vehicle is new...

• Trailer Left Turn and Brake Lights Sometimes Do Not Work on Trailer Towed by 2014 Kia Sorento
• This is a textbook example of a bad ground connection. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and...

• Troubleshooting Left Trailer Tail Light Always Has Power With 2017 Kia Sorento
• The first thing I would do is check the test the wire running into the powered converter. It is unlikely you have power here since I'm assuming your vehicle light isn't always on, but it doesn't hurt to check. Assuming you do not have power, I would go ahead and inspect the other wiring for a short just to be sure. It also wouldn't hurt to check the ground connection. If all of this checks out, the problem is the converter box and the wiring harness # 118583 will need to be replaced.

• Troubleshooting 4-Pole Wiring Installation
• Thank you for your many purchases from etrailer! We appreciate your repeat business and your trust. The item you installed was Curt 4-pole harness kit # C59236 which is a confirmed fit for your 2012 Kia Sorento. Your trailer's right stop/turn light staying on whenever the trailer is plugged in could indicate damage in the converter but it could also be something as simple as a bit of trapped water or dirt, or perhaps corrosion inside the electrical connectors. It is easy to test to confirm. I...

• Troubleshooting Trailer Tail Light Harness that Keeps Failing on a 2015 Kia Sorento
• Since I don't know what wiring harness you had installed on your 2015 Kia Sorento I am not quite sure as to what could be the issue other than a faulty installation. We do have 3 different wiring harnesses depending on your vehicle style. If you have the V6 model with a factory tow package then you would need part # C56332. If you have the I4 model without the factory towing package we have the part # 118583. I would be sure that whatever harness they are installing is correct for your...

• Troubleshooting No Tail Lights On The Trailer Using A Tekonsha 118269 On A 2018 Kia Sorrento
• It could be an issue with the module and we can easily test to be sure. You will need a wire probe like the # PTW2993. We would have you go in and test the wires going into the module. If we are getting good signal on the tail light wire going into the module, but not coming out of the module, we will know the module is bad and will need to be replaced. Tekonsha Wiring harnesses do come with a 1 year warranty. If you do not have signal going into the module, this means there is an issue...

• Locating Trailer Light Fuse on 2016 Kia Sorento
• I took a look at the online version of the owner's manual for your 2016 Kia Sorento and if it's equipped with the tow package there should be a 30 amp fuse for the trailer wiring connector inside the under-hood fuse box. For its specific location you will want to check the diagram on the fuse box lid (under the lid). If you find that the fuse isn't the issue please let me know a bit more detail on what is going on such as if all the lights aren't working or if it's just a certain circuit...

• Circuit Tester to Use to Test Pins of 4-Way
• If you are trying to test the pins of the 4-way on the part # 118506 for function the # PTW2993 would work well for this. Or if you were trying to test for voltage on the wires of the harness this would work well too. I attached a video that shows how to test the pins of a 4-way as well.
