The correct wiring harness for your 2015 Kia Sorento is the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56256 which will work with both 2.4L I4 and 3.3L V6 engines. I have attached an installation video of this harness installed on a similar 2015 Kia Sorento for you as well.

If you would like for me to recommend any other items to complete your towing setup please let me know what those items are and I would be happy to do so.
