Anyway as far as I can tell, the ignition coil centre terminal is connected to the distributor cap

I am then left with the black push on terminal (with an additional plug in component that is connected to the mounting bracket screw) and 2 Nr green wires.

Logic says that the black is the negative (-), but Dogwoods diagram contradicts this!

Can anyone help or have photos ???

DIN spec wiring uses brown as negative and any other colour for positive also very common to use black for coil pos and green for the trigger.
