Trailer Wiring Harness for a 2012 Kia Sorento  

Question:

Expert Reply:

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 your Sorento. If you have an EX or LX V6 with factory tow package then you can use # HM11143965. If you have a model that does NOT have the factory tow package use # 118506.

If you do not know if you have a tow package or not you can have the dealer run the VIN to determine if the vehicle is equipped with the tow package or not. I have linked videos showing how each harness installs.
