I just posted that info..

Unplug the sensor and put an ohm meter across the pigtail to see when the sw opens/closes...then put a gauge on the system High Side and put the a/c ON ..watch the gauge to see if the sw opens/closes to specs

The cut-in is 16 bars, the cut-out is 12 bars ..[ if you have the red sw]..which you should gave on that chassis.

If sw is green , specs are 20 bar and 15 bar ,
