If you open the back hatch. Remove the tread panel. Then remove the three screws holding the driver’s side cargo panel and start popping back that panel a little. Do not need to remove the whole panel just a bit to pull back a bit. It was behind that panel. Pre-wired for a tow harness but apparently the new harness hasn’t been released to markets yet (according to KIA dealership). It’s an 8 pin male plug.

Did you ever figure out the pin-out schematic for this plug?

I looked on the site and they didnt list anything for 2026.. I ordered a similar one from amazon for a 2025 and it did not fit..
I managed to build one from various parts..

Yes the '23 & '26 dashes look a bit different. The ProClip would mount in the blank space between the two screens, behind the upper right side of the steering wheel.

2026:

Of course you could just contact ProClip and ask. Squeeky wheel gets the grease!

I just called a dealer in my area (Roseville, CA) and they told me Kia has released the factory trailer wiring harness for the 2026 Sportage. Their price is $283.00. I don't think I am willing to pay that, but it is good to know the product is now available. Hoping Curt or another knockoff becomes available soon!

If you can find out the part #, there are usually Kia dealers that sell online at a decent discount. They should also be able to find it via your VIN #.

I'm scheduled for installation early December for the wiring harness, so if this isn't answered before then I'll try to respond back then with the part #

It’s a pretty darn easy DIY job. I didn’t even bother fishing it out to the bottom of the bumper. I won’t tow that much, so just left the connector curled up under the cargo floor and will lay it out under the bottom hatch seam to the trailer when needed:
