AC Low pressure switch

I have a 2018 f250 6.2 xlt, just replaced the ac compressor due to it leaking. Put the gauges back on it to find there is a restriction causing a vacuum on the low pressure side. However the compressor never disengages. I’m unable to locate a pressure switch on the low side and only see one on the high side. Any suggestions on where to locate it or if it has one?

Looks like this system only has one pressure transducer.
