Glad you got the wheel off.
What hub adaptor and wheel are you fitting? I installed a Momo pattern wheel on an accessory hub from Classic Alfa.
The horn wiring was simple, so simple I've forgotten the specifics but I'm sure someone will chime in.
Basically, the typical aftermarket Momo-Nardi horn button has two spade terminals. One of these connects a wire going down through the hub to the circular contact strip. The second wire is a ground which fits between the wheel and the hub and contacts one of the 6 wheel to hub fixing screws. I don't recall using any wiring from the airbag wheel contacts.
Anyway, it's pretty straightforward on the typical Momo-Nardi style hub but I don't know about others such as Grant.
Good luck and keep us posted.
