In the GM 7/8-pin HEI, the module converts the AC signal from the variable reluctor pick-up {on pins P & N } in the distributor to a 'square wave' tach signal {on pin R} suitable for MegaSquirt-II. The falling edge of this square wave is used as the trigger event (which becomes the rising edge when the optoisolator inverts the signal).
