Hi all, I'm doing a custom air conditioning setup in my s14 since stock parts are hard to find/ too expensive. I have a few questions and would appreciate the help, thanks in advance. I'm a newb to A/C stuff. Btw I'm using an s13 sr20 blacktop compressor.

Firewall connections... There is a large diameter connection and a smaller diameter one below it. Which connections are high/low pressure and in/out?
I assume these aren't "AN" fittings, so what are they?

Compressor ports... The port closest to the pulley is high or low pressure? And which one goes to the condenser?
