Can I bridge the POA ports for the expansion valve and straight up remove the POA? I am looking at the delete kit and scratching my head. https://originalair.com/73-early-74-buick-apollo-ac-poa-delete-kit-15-51 I have a high pressure switch on the R4 compressor model that I have, so to me the question is what does the POA valve delete for $99 really do? ...nothing except in theory provide a port. BUT I am smart enough to ask the good guys here on whether this is true. OR can I just modify my POA to not regulate pressures and temp thus leaving it in place and wiring the pressure switch?
