The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - AC compressor relay and Trinary switch wiring question

I am adding a low pressure cut out switch since the compressor is not cycling and freezing the evaporator. This is an updated diagram that I am asking Ls1nova71 to look at and verify. I moved the AC Request wire to terminal 87 on the compressor relay. I did that so the idle is bumped up only when the compressor clutch is on.
