I have managed to sus out most of the wiring for the Bosch Motronic system using a running car and found that the system only needs three wires to run the engine(+1 to engage starter)

Black /green---- from Ignition
Pink ------------ 12v from battery(i think)
Pink/white------?????? seems to be to ground but dont want blow the system,


Does anybody know what pink/white maybe?.

Sorry if its obvious but i'm not great with electrics.

try alfaowner.com,they seem to know what they are talking about

Try lancia stratos supersite they have a lot of replicas with alfa v6 engines fitted and they are a friendly bunch and have good forum site im sure someone will know the amsweron there.
Hope this helps.
