After looking again, I need to modify my procedure on the horn portion:
I was wrong about the screws I think.
The flat head screws DO have rubber washers on (2) of them and not on the 3rd.
These screws insert into the bottom portion of the horn ring and into the wheel itself through the larger holes on the top portion of the horn ring.
The Black phillips head screws insert into the top portion and have a PLASTIC washer on them.
I guess all screws should be tight, but I remember loosening the one flat screw WITHOUT the rubber washer just a touch to keep the horn from staying on.
YES, the outer spade terinal should be at 12
o to clear the horn pad cutouts.
The wiring is as follows and makes sense if you look at it:
(2) black wires; one is screwed to a silver allen screw inside thye hub. The other connects to a brass ring on the bottom of the hub...so...power comes from the one connected to the bottom ring and should be installed on the spade terminal of the OUTER HORN RING so when you push it, you complete the circuit.
I hope that clears things up.
