Stupid Low pressure A/C Port!!

Where the hell is it?I have a 1996 2.8 A4 and i cant find it,just one with what looks like a switch,but the adapter of the refill kit doesnt it on that.
So where the hell am i supposed to connect the 134a refill?
And before anyone asks, No leaks, just changed compressors, but had the system drained before i removed the compressor,now they want 140.00 to refill, lowest i heard was 100.
So help me out :)
oh its not by the passenger firewall either,i found the Other port,Thats by the front grill.
Grr!

Argh,no one knows?:(

your best bet is to look at the compressor and trace the lines till you find it

tried that, i think the only thing to do is remove the switch on the low pressure side,but the adapter doesnt seat right,i think the shops use the other port since they have the machines.
I think i'm F'd :p

Well,Finally gave up and wound up paying 100.00.
They had to do something to the usual hose to make it work,25 minutes later, My car is cold as ice again!
Awesome!
