Hey Jeff, we had a customer with a hybrid Sportage just like yours leave a review where they detailed how they installed their Curt trailer wiring harness # C99DR on their hybrid model. I attached a picture of it below where the discussed running the power wire for you to check out.

hey jeff that is my question awhile back when looking for the same-- so the positive post you want to tie into is under the hood on the right wi-- the fuse cover on my 2024 has a big red + sign-- pull the cover off and it is one of two posts under the front of the fuse box sticking up -- i put a multimeter on it and it is hot and so that is what i tied into and ran wires to the back--once i figured it out i got it done-- hope that helps
