When I got out of the Z4M today I noticed that a small plastic part had fallen off the door. It looks like it just clips into the door card. A small plastic emblem that says "AIRBAG" on it. On the back there are 4 little arms, the 2 outer ones look like they would clip into place but one of the little arms has snapped off.

I have had a look on realoem and it looks like I need part 18 from here. However looking at realoem's illustration there is something coming out the back of the plastic tag. Should this clip in tag be attached to something? Do the airbags need this plastic tag wired to something to work? Or can I just buy a new plastic part and clip it in?
