I had been asked about how to wire up ac with the stock 5.0 and how to increse rpm for use with a winch or welding. I have included some diagrams that show the factory ecm connector and what they go to.
Pin 10 is for the ac, it should be run threw a switch and a relay. The pressure swich could be omited but I wouldent recomend it.
Pin 21 is for idle speed control, if it is put thew a switch to pin 37 it could be toggled on to connect the circuit, this would increase the rpm as if the ps rack were at full lock and require a boost in rpm. This would utilze the iacv.
I have included the diagrams for the mustang and the crown vic, I do have other diagrams depending on what people need. Hope this helps.
