I need the pinout to make an adapter for the 3 pin connector to 16 pin OBD2 plug. Does anybody know?

Wiring to adapt the 16-pin OBDII plug on the interface lead to the Alfa 3-pin diagnostic connector will depend on which ECU you have...

If you have a Bosch Motronic M2.10.3 ECU:-If you have a Bosch Motronic M2.10.4 ECU:-If you have a Bosch Motronic M1.5.5 ECU:-You must also take a wire from pin 16 on the OBDII interface lead to a +12v source (i.e. direct to the positive battery terminal).
