Ok, i have a 1993 Chevy Suburban K2500 5.7, I just replaced whole ac system with all new components, however i keep springing leaks in places such as compressor and hoses, even though they were both new, so i replaced them again and seen the back of my compressor has a slot with a snap ring in place, where i assume a high pressure switch can go, but i didnt have one, nor do i see any wiring harness anywhere. So i sprung another leak after i hooked it up again this time in the place where the high pressure switch could go. So my question is, am I springing leaks everywhere due to no high pressure switch? I live in a very hot climate Yuma,AZ. So please any input will help me, as I nor anyone can figure out why. Also If anyone can help with a wiring diagram for a high pressure switch, as I dont have a clue how to hard wire it in. Or can I use a pressure release valve? Like I said any input is highly appreciated as I cannot do this.Being that my compressor is leaking from the snap ring area where the switch would go, can i just replace oring? Thank u in advance
