This switch has 4 terminals - I used an ohmmeter to figure out that it can is always open on two terminals and always closed on 2 terminals, depending on what position the switch is in. So, if the plunger on the switch is all the way out, one set of terminals is open and the other closed. When you depress the plunger, the first set is closed and the second is open. Does that sound like it will work? I haven't tried it yet, but it seem is I should be able to just wire it up so that when the clutch pedal is at the top of its travel (plunger in), I can use the terminals that are open at that point, and when I depress the clutch, the switch will close and ground Pin 10 on B58. Sound reasonable, and feasible?
