Yes I agree this is the part where i'm like fuck this i'm over it sell up. But since I started it I've been trying to do the whole conversion the right way the first time so it isn't a huge mess and thus far that has succeeded. I do have the opportunity to have a bloke do the whole thing for me, but it means I don't get to learn and understand what has actually happened and how it works. In no rush to get it done so if I were to attempt to wire it myself I'd map out what has to happen and take the time to do it.

What you've said is making sense to me for the engine loom itself. What did you do about the existing 4AC loom that is also attached to all the headlights etc and has the positive terminal on it, did you use the original Pos terminal or the Smallport one?
