Wiring help please

Ian, I don't understand what you mean by saying it is a shame that the three were not separate and could be installed separately?
If you have an old harness to go by, and the wiring schematic, you can figure this out.

I understand that there are three different groups but they cannot be installed separately...the wires seem to be intermingled hence creating much of the mess. If I think back to my MGB, there were no where the same number of wires in the engine bonnet and it had electronic ignition as well. Actually, come to think about it, the only difference was that the MG didn't have a power steering.

My wife is dragging me away for 3 or 4 days..I am going to take both harnesses and the manual to see if I can fix my previous buggering.

Ian.
