The pressostats are not the same, at least on my '98 V70. The 2-terminal switch by the firewall is just a switch -- closes at 45# to allow the compressor to run, and opens at 20 or 25# to stop it. The 3-terminal one near the fill port is a pressure transmitter that gives a pressure signal to the engine control module.
