'95 S420 A/C system pressure question

What is the system pressure at rest? My gauges both read 65 PSI. Today was the first time I tried the A/C and the air just blows warm. I saw a sticker that dye was used last August so it must have had a leak before. Also the refrigerant pressure switch has 3 wires to it. Which should I jump to see if the compressor kicks in?
