Wendell said: "The system uses two pickups and compares the signals." The long series of cruise controls that I have installed on many different vehicles used only the coil sensor unless I was installing on an automatic. The documentation uses the term "electronic clutch switch" and there is no physical clutch switch. Depressing the clutch on a car with one of these systems engaged causes the engine to increase speed momentarily and then the cruise shuts down. Since there aren't two signals to compare, I conclude that the unit watches for an increase in engine speed that is not consistent with normal vehicle acceleration. Mike
