Hi

I do not know your experience, but mine was that the white switch with the arm is on the clutch pedal and the black and white block is the real one. I mistook the clutch pedal for the brake pedal. When one is upside down looking under the dash, my orientation went to the clutch pedal. The brake pedal curves up and toward the middle of the car and the pivot point is nearer the throttle pedal.

I live and learn...
