Joe shared his colorized drawing with me last night. With his help I've gotten this far without going to my public storage unit.
Its not finished, there are a few loose ends.
The 3 port vacuum switch, #12A111 in John's picture … its a "vacuum" sensing" 2-way valve. I've drawn it in, but I need to figure out what Ford called it; haven't been able to remember or figure it out yet.
There are 2 other in-line devices: #383004-S and #373846-S. They are probably one way valves (check valves) or perhaps a signal delay. I'd like to figure out their purpose & name too.
Thanks Joe …
