Does anybody know where I might be able to find the horn switch and plate that mounts to the steering column. Does anybody make an aftermarket part that might could be retrofitted? I replaced the horn ring wire that goes on the inside and solders to the brass/copper? ring, but I'm missing the plate and switch that mounts on top of the opening on the column for the wire from the wiring harness to plug onto. On a side note, I've read many threads here and gone over the description in the manual, but my head just can't grasp how the horn actually works.
