Stuart,
Thanks for the diagram. When I disassembled the steering column, the only wire hooked to anything was a bare wire protruding from the bottom of the steering column. There was no wire that was connected to the horn buttom itself.
Are you saying that the wire should go directly to the horn buttom, then when you push the buttom, one of the tines touches the steering column (grounding it), causing the horn to tute.
The diagram shows the button wired directly to power.
Thanks
David
