420 SEL. I have multiple ports (4 of them, one on top, one on compressor, one on the lower line to compressor, finally one on the front of the car, right next to the cooling fan)

Which port is the one you hook up to in order to charge it with freon?

I have two ports on my car, one high pressure and one low, the low pressure port is on the driver’s side with a blue cap.
If someone else does not post first I’ll check in the daylight. You’ve got no caps on the ports?
