As far as I know, pin3 is ground, pin2 is signal for ecu and pin 1 is +12v from dme relay. But couldn't find 100% confirmation about that so I used m52tu intake cam sensor which is hall sensor also and direct replacement to single vanos head. Only two tabs needed to be removed from connector to fit it single vanos wiring harness.
