Had a similar problem with this switch. The spring loaded mechanism needs to be in constant contact with the small square outside/round inside plastic trim (Call it tab A) that goes on the steering column.
In order to achieve this you need to very carefully reassemble the bottom plastic piece and top cover to the steering column. The bottom piece is the one with the hole for your key on the right and choke on the left. This piece is critical as it holds "Tab A" in place. If your lower cover is cracked and cannot hold "Tab A" in place then the contact will be broken and the horn will sound all the time.
I think the way the horn actually works is that power is going to the system all the time and pressing one of the horn buttons breaks this circuit and causes the horn to sound - the piece I called Tab A (which is not a tab at all btw) helps keep this system closed.
There is a wire that goes to this Tab A piece (I think, trying to recall what this all looked like) that connects onto the Tab A tab. You may have discovered that short of fixing your horn simply taking this off will keep the horn from sounding all the time until you do fix it. The other (extra) wire you speak of sounds familiar - I believe I saw similar when working on mine - I think (wizards on the board may tell us otherwise) that it is not important - or at least I could not figure out what it was for.
Let us know how you fix this - as I said - went through similar problems and finally ended up fixing late at night on a sunday and don't recall exactly the layout. You may want to also check the archives as it seems I found something in there when I was having this problem.
Happy driving and quit honking at me.
: there is a wire coming from the igntion where the key goes in and it dosen't hook up to anything. And the horn won't go off any Ideas on where this might hook up to. The wire is brown with a greenish stripe on it. Please e-mail me with Ideas. Thanx
