3.5 Olds Intrigue 2002 service ports

[Magster60]

Hello. I recently charged my a.c. on 3.5 intrigue & stupid me starting putting it in wrong port. No big damage. Did find right low service port next to the one. So I want to know what port did I mistake or for. Its along firewall with green cap, behind brake fluid fill. See pic.

2002 vehicles have quick connect fitting for R134A systems. The ports are different sizes so it should be close to impossible to connect to the wrong AC port. And they are usually color coded red and blue (the hose connectors. What hose connection did you have to fill the AC system?

There should be a plastic hose that has a port valve similar to a fuel pressure port. It has a green cap. It is the EVAP service port. Should go from the intake (purge solenoid) to the charcoal canister.
