Hey Larry, thanks for the information! To add a 4-way wiring harness to your 2023 Kia Telluride X-Line you'll need the Curt item # C29ZV. This T-Connector plugs directly into the wiring harness behind your rear tail lights. Since your trailer has regular light bulbs you won't have to worry about compatibility issues. It's the LED trailer lights that often times require resistors like item # P230004A-2 to work with newer vehicles.
I saw you were looking at our etrailer hitch item # e45ZR. It is custom fit for your 2023 Kia Telluride X-Line. It has a 2" receiver and a 5,000 lbs towing capacity.
I recommend using the No-Drill Mount for Electrical Mounting Bracket - Short item # 18140 and the item # C42CR bracket. to secure the 4-way connector to your hitch. This will put it in an easy to reach spot and prevent the risk of it falling onto the road.
I've linked installation videos below for both parts so you can see how to get them installed.

I'll buy the C29ZV kit. My 12' trailer hauls up to two of my bikes: a 2000 Triumph Legend TT (my "new" bike); or my '75 Norton Commando; or my '65 Triumph Bonneville. The aftermarket 2" hitch was on the car when we bought it a month ago. Thanks for your help.
