Air Conditioning switch questions

[Toby_Goodmk]

I am converting over from a hot air car to intercooled and have purchased all new components for the AC. Now the confusing part about getting the sensors is the one on the back of the compressor. I have access to all kinds of new AC parts, but dont have a clue how to determine which switch is needed. It appears there are 1 and two wire ones, there also appears to be different colors which mean different pressures? I have come across some oem numbers but they do not cross to Global/omega/4 seasons numbers.

Any ideas what pressure values are needed, and wire counts? I guess on the wire count I can look at my harness tonight.
