This should do it for you. As far a color of wires, etc., it is possible that over the years anyone could have swapped wires and not retained the same color. If it were me, I wouuld take my volt meter and using the schematic, verify each circuit is going to the correct component and will ohm thru (not broken). The wire doesn't know what color it is passing current through. You could take pieces of tape and tag each one as you go so you don't get confused.
