Does anyone know what makes the ignition buzzer work on a four speed car? I know there is a contact in the column but does it have anything to do with the clutch switch or the reverse light switch. I checked the wiring diagram in the AIM but it crosses 3 pages and is not very clear. The reverse linkage from the column to the trans is not on my four speed car due to headers and the clutch switch is evidently not connected either.On my automatic car it does work when you open the door with the key in but that car has working reverse lights and no clutch switch.
