Default Sanden 7176 plumbing

Hi guys I'm trying to plumb up my custom mounted a/c compressor but I can't find any info on what the high pressure and low pressure side what side goes to the condenser and what side goes to the evaporator/firewall

I talked on summit racing and he said the larger port goes to the condenser and smaller side goes to the firewall but on most compressors it's the other way around and I'm confused on what to believe isn't the smaller size usually the high pressure and larger is the lower pressure

Pressure side ALWAYS goes to condenser, suction to evaporator.

Turning the pump will tell you which side is which. Pumps only have pressure and suction ports. Finding which is which is easy.

#10 goes back to the dash
#8 goes forward to the condenser
#6 dash to condenser

Any aftermarket or universal system will use this general layout
