When I say the ac control circuit, when you turn on the ac @ the dash, it tells the ac control circuit to turn on (ingage) the ac compressor clutch, the cooling fans, interior fan, increase the idle rpm. I belive there are 2 pressure swiches a high and a low which cycles the compressor and shuts it down when pressure is to high or low. A Haynes or Chilton manual would help you as they have schmatics in the last chapter. I can take a look at a friends and see what I can find, give me a few days.
