That's brilliant thanks mate. It looks like I'm on the right path then, what I've done so far is as per your set up bar the reg/rec. My old a/c zong was the same as yours with yellow and pink. The new motor has what I think is a three faze magneto and has three yellows, no pink. I got a matching reg with three yellow input wires.
So now I think I'm in a possition to finish the wiring, I just need to have a look into finding a smaller battery and know where it's going.
Lastly about the main live for the ecu, is this permanently attached to the battery? I assume to maintain memory.
