On an '88 5ktq, the low pressure port is behind the firewall on the
passenger side -- in the space where the wiper motor and heater fan live.
The low pressure side has a pressure switch with a single wire lead
connected to the shraeder valve.  I needed to remove the pressure switch to
get to the valve.  I also had to fake the switch's input to the system to
get the compressor to run.

YMMV.
