Yeah ... I saw that, and may of the other search results, including searching images but my engine looks nothing like that one. My 2005 Lexus RX330 on right. I took apart the air intake to look underneath and still couldn't find it. Thanks for the response.
The low pressure port is on the line that comes from the firewall and goes directly to the inlet of the A/C compressor. Very likely it is rubber half way, then metal the rest. On the A/C compressor, are 2 lines, one is high pressure, will go to condenser in front of radiator (looks like a skinny radiator), then to firewall, you want to trace the other one.
The low-pressure line is near the firewall (passenger side). It has a black cap that needs to be removed in order to access the connection.

Low psi location is 10 inches below positive battery terminal next to the sight glass, not a good spot when engine is hot. Not well thought out when engineered. Got it done though and at least this post got me looking in the right area. Thanks
