The ignition module 0 227 100 111 will work as a direct replacement for the alloy cased 0227 100 017.
I have swapped mine over, My car has the two-wire VR inductive pick-up distributor. I used the module from my written off ALFA75 which has the three wire hall effect pick-up. It works perfectly with no over-heated coils, poor performance or misfires as long as you have the whole ignition system correctly wired.
My alloy box 0 227 100 017 amp had these colored wires they connect to the 0 227 100 111 as follows.
black/white.......................................connect to #1
black...............................................................#2
green/black .....................................................#4
The 2 wires From the distributor are as follows
green and shield
green...............................................................#5
shield...............................................................#3
#6 and 7 are not used
You can use a BOSCH 0 227 100 111 a Tridon TIM 017, Fuelmiser CM413 or a BERU ZM 001 as a direct replacement for the 0 227 100 017 alloy box.
You will need a Bosch EV1 7 pin male connector. No other parts need to be replaced or modified.
