Default AC Low Pressure Port Location (Engine Bay Next to Oil Cap?)

I'm charging up my system, and just wanted to make sure that I have the right port. I know the recharge bottle fitting only works on that one, but thought that I'd ask first.

Also, does anyone know what the correct recharged pressure should be?

Edit....think I answered my own question. The coupler on the recharge bottle does not fit on the AC port in the engine bay by the oil filler cap. Anyone know where the other port is?

Tnx, gents.

I think it’s down behind driver side wheel liner. You should see a small black cap.

The port is near the firewall on the left (US driver) side of the car.

You need to look at a chart of pressure vs. ambient temperature. It varies from 30 psi @ 65F to 55 psi @ 90F. Here is a chart I found on the internet.
