putting jack etc. back in trunk.....




I admit that I don't even know what this thing is:

...but where does it go? (and while we're at it, what is it?) I was able to figure out how the jack and lugwrench go in, and I plopped the lugs in with the spare fuses in a little nook (or is that a crannie?) if there was more of a "toolkit" with the car, I didn't get it (tho' the tire wedge is in there as well).
This cover to something was floating around in the trunk:

anyone know where it goes? it says "FCC ID DOZ 2225" which doesn't Google well.
