I wan't to connect a manometer to the AC system on my '96 A4 1.8T but I can only find the "valve" on the high pressure side. The high pressure valve is on the condenser. This makes me think the low pressure valve could be on the vaporizer but it would be kind of wired to put it so far from the other one and behind lots of interior. Anyone know where it is and if it exists?
