loosen the two bolts that secure the steering wheel column to the dash, drop it enough to give you the clearance you need to get the cover off. Be gentle with the cover and the screws that attach it. Its pretty fragile. Once that is out of the way the combo switch is easy to remove, its a clam shell like device, splits down the middle. no reason to remove the steering wheel but even if you do its not hard. Push down on the horn button (battery disconnected) rotate about 5 degrees CCW, and it will come off. then there is a single large nut holding it on. But again I see no need to remove it.
There is a sliding contact that operates the horn, its a thin copper arm that extends out from the side clam shell part that houses the hi low beam and turn signal switches. Just be gentle with it, the plastic part it mounts to breaks easy.
