High/Low AC pressure ports--location?

Is the high pressure port the one next to the radiator? It looks to me like the AC line comes off the compressor and connects to the condenser. I read somewhere, IIRC, that is the high pressure port. That would mean the low pressure port is the one next to the intake/PS gizmo/brake fluid reservoir.

Reason for asking is the 300E is blowing ambient air. Was working OK last year.

It's got the 134a sticker, so I was looking at just adding a can or two.

Thanks in advance.
