Can anyone tell me where the low pressure A/C fitting is on a 94 S4 (I believe it is the same A/C system as the 94 100). The only thing I can see is a wierd non-standard fitting on the back of the compressor. I really need to push that Bentley purchase up higher on my automotive shopping list. Anyone have an extra/used one? Thanks. - - - - - - - - - - - - Dwayne Cosby 94 S4
