The link that Bill posted shows a switch that has a tab on the bottom. That goes into a slot at 5 o'clock on the TF steering wheel. The AD steering wheel has a small hole at 7 o'clock, but the repro switch that I got doesn't have the tine. Without that keeper the switch wants to rotate as you torque the steering wheel nut. In my case the switch rotated until one of the switch rivets got close to the horn button contact. It was super sensitive until I figured that out.
