I have been adding content to this FAQ. I have received several photos but still need good shots of a 72 3.0CS under dash, all relays need to be visible, even if two pics are needed including wires in the sockets. Also needed is a clean pic of the choke relay on the booster mount and the CSi relay that is also there I believe. Please reply here and not in the FAQ as I have removed all prior comments. As you will notice I have added 72-73 and 74 US wiring diagrams. Thanks for everyone's help so far.
