For your 2019 Kia Sorento, I recommend you start with the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118583 and then add the 7-way adapter # 37185. You will then attach the white wire with the ring terminal to a bare metal ground on your vehicle frame and then use wiring # 10-1-1 to run the 12V wire (black on the adapter) to circuit breaker # 9510 and then to the positive terminal on your vehicle battery. You will not need to connect the blue or purple wire on the adapter so you can tape them out of the way. The blue wire is the brake controller output which the RF controller doesn't use, and the purple wire is the reverse light wire which doesn't need to be installed but can be to your reverse light wire behind your tail light if desired. You will also need the no-drill mount # 18140. This will make your wiring compatible with the Tekonsha Prodigy RF Wireless Brake Controller # TK94FR.

Then you will need trailer hitch and I recommend the etrailer.com Trailer Hitch Receiver # E98843. This will have a 2 inch receiver and will require no drilling for installation.

Finally you will need a 2 inch ball mount with a 2 inch hitch ball compatible with the R-pod. I recommend the etrailer.com ball mount kit # 989900. This will give you the ball mount you need that is compatible with your hitch and the trailer coupler for a level transport. I've attached an article to assist with choosing the correct height.
