I tried to snap a photo of inside the bumper left of the hitch. The bottom of the photo is where that white divider tab starts in my previous picture.
I just picked up my cover from the dealer, and this is what you get. Hitch cover, hitch cover adapter insert, and a pin. The hitch cover adapter fits into the hitch and the bottom tab snaps into hole at the bottom of hitch. After that, the insert and hitch cover have ridges on the side that snap, kind of like a zip-tie, except it isn't permanent one way as you can pull it back out. Not easily to pull it back out though, but need to wiggle and pull firmly. Haven't put any miles on it yet so not sure if it will stay as it was noted that some are falling out. But to remove it, you use the tab of the insert to remove from hitch, not removing the cover from the insert, so the hitch cover isn't wearing out the ridges of the insert. I have no idea what that pin is for or where it goes if anyone can help with that.
