Sorry, all my literature is for a 123....

" I do not see a pressure switch in the system, when I short the switch on the evaporator, the aux fan on the radiator comes on.
And want the heck is the red wire to the a/c temp control switch? It does not show up on any schematic I have seen."

Do you mean the switch on the Receiver/Dryer rather than the evaporator?
Do you have two switches on the plumbing at the Receiver/Dryer ?
