I replaced the GM R4 compressor which housed the high pressure cut out switch on my car.
The compressor I am using is a Sanden SD7H15 and does not have a provision for a high pressure switch.
I do have a 3/16" fitting on my liquid line for a cut out switch. The line I have came from a late 80's Camaro and that switch was for controlling the electric fan and specs show it is Open: 255psi Closed: 340psi.
I am looking for something could potential control both the fans and cutting the compressor should the pressures get to high.
Is there something out there that would fit what I am looking for?

Sanden SD7H15 is like saying I had a cup of tea. There are many different variations of that body compressor. 4-digit number tells the story.

The compressor is a Sanden 4805.

Compressor, if Sanden, should have a high-pressure pop valve.

Yep! Mine has the same GV rear head.
So I should be ok without a high pressure cut off switch as mine has the pressure relief valve?

If your pressures are in check. Pop-off should be enough. HPCO switches were popular. Not sure if they are around much these days.

This might work as well.
