Lavanaut...
thats identical to mine....and it is a 8002 adapter
Ok, so the small gap isn't of any concern, but naturally the fact that your horn doesn't work is. The two aren't realted though.
I had just a single wire that I removed from the stock wheel that I fed through the hub adapter, and clipped to the back of the Momo horn button. The horn button has a brass-looking contact on the back, when I installed the button in the adapter I made sure to put that side in first, so that the metal contact was pressed/wedged firmly up against the hub adapter. Worked with no issues on the first try.
My hub adapter came with no instructions at all, just a piece of paper that said, "WARNING! READ INSTRUCTIONS COMPLETELY BEFORE INSTALLING"...and nothing else.
I took a bunch of pics during my install, let me know if there's something you're not clear on..I'll post pics if I think it'll help.
