Chris:  From pg. 3/9 of an later 1.8t Audi B5 wiring diagram (and a 41/4 of a later Jetta IV 1.8t Bentley), my interpretation of the pinouts are:

1 = hot to primary coil
2 = secondary coil ground
3 = hot signal from the ECU to the POS
4 = POS ground

Now if it wasn't for that nagging "dwell" issue suggested by Mark S., this looks like a winner to me.  (Sounds too good to be true - replace all the coils and the POS for a fraction of the cost of going with old style OEM parts).

Hey.  Progress!! (except for those nasty Bremi recalls -which I am sure won't happen again).
