You want the switch that is closed when the clutch is pressed. Also, make sure you use a heavy enough wire, when I first wired the racer, I used speaker wire, when you tried to start it, the wire got hot but the car wouldn't start.... After I replaced it with 14g it started right up.
Can I drive it at the Anniversary meet after you get it finished?? Not sure where we'll be meeting for the 20th, but I'll see you there
