HI Bud

There is no low pressure switch.  This system has a high pressure trinary switch that has a lead coming from the BCM.  I would not play with that switch unless you want to buy a new computer for your car.  Add refrigerant and see what happens.  Let me know what your pressures are and I'll help.
