I can't answer your question, but just in case you have not researched this much, you are fighting something that many, many owners of 91, 92 and the native R134a 93 240 owners have fought before, and the consensus is... wire it to come on with the compressor or the AC switch, because the pressure either never makes it up there or the switches just can't last.

Without much personal investigation of this, I just "blew it off" as another early 90's emergency ECN stimulated by the Montreal protocol. ECN is shorthand for engineering change notice which is doublespeak for "emergency fix."

Who is going to go sit in traffic and hook up a high side gauge to see the pressure crest the spec for the HP switch? Couple beers on a slow day in July maybe?

Also a matter of consensus: that fan helps a lot. Sure it is noisy.
