Locate the low pressure switch. Remove this and you'll find a regular 
Schrader-style AC valve on the low pressure side. Not the R134a valve, but 
the old R12-style which is still used on switch connections etc. This valve 
works great as a low side connection. If you need to run the compressor 
(necessary when filling), you just bridge the connectors in the wiring 
harness connecting to the switch. BTDT..
