Sure that's not the obd2 evap test port?
It's right by the plumbing for the AC up against the firewall.
Has it got a green cap on it? Does it have plastic lines running to it?
it's got a green cap. Might not be connected to the AC, couldn't get in close enough to tell if the lines are plastic or not. So what's it's purpose?
It's an evap test port. Follow the line. One end will go to the canister.
It's used to test the fuel evaporative system. Some hook a smoke machine up there. Some hook a mityvac and magnehelic gauge up there.
