Question:
Hi, I have a 2025 Kia Sorento EX Hybrid which says it is pre-wired for the tow package. I cannot locate where the wiring is and which harness my vehicle would take to connect this. I have read several articles and there are differences between the LX/S models and the EX. Also, there is no mention of what to do when the vehicle is pre-wired. Can you shed some light on this? Thanks

Hey Mike! I saw your were looking at a 4-way connector. I checked with Curt and the correct one for your 2025 Kia Sorento EX Hybrid, is their T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # C63RV. This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. This will provide you with a 4-way connector.
I have linked an installation video below that will show you where to find the connector. You can skip ahead to the 3:50 mark to see it.
If you don't already have a hitch, I recommend the Curt item # C37RV. This is a class III hitch with a 2" receiver. It is custom fit and bolts to your Kia with included hardware.
What kind of trailer are you towing and does it have brakes?
