Dear Papa: I have always recalled electircal diagrams as affected by Law # 3 of the Seven Laws of Alfa Design and Construction:
3) THE LAW OF ELECTRICAL CHAOS
“All Alfa Romeo Cars shall be wired at the Factory by a cross-eyed, color-blind worker, using whatever supplies are within reach. All wires shall change color-code at least once between energy source and component. All grounds shall be partially insulated.” This tends to guarantee that the owner of such vehicles will eventually be intimately familiar with its electrical system, since he will need to trace out each wire, then rewrite his Official Schematic, which will differ from all others in at least one area.
Every Alfa Owner should be entitled to his own self made electrical diagram.
