I tried to find a diagram on Kia site and Alldata. None to be found. I'll try to walk you through it. If it is not good enough I will opt out.
The spring retainer wire should be a "U" shape. The bulge loop at the bottom of the "U" shape slips under the Phillips screw and the two ends go on either side of the bulb with the loopy/hook wire end will anchor under the tab with a groove in it. Wish there was a picture but this is the best I can do to explain it.
