I personally would not turn on the fan when the compressor is on. That means when the compressor kicks off the fan will go off. Wire it up as original which will turn on the fan when the high side pressure is excessive. That's really what the fan is there for, to bring down the high side pressure.
How's the airline business? It sounds like things are picking up for you guys. As for me I'm currently unemployed and doing my best to change that.
Have a great day,
