Converting factory AC to use R134a

[ricachon7]

Excellent! Thank you kindly for the diagram. I failed to mention that I have swapped in an ls engine and installed a Sanden compressor. I have all the original components there. I will be updating the POA valve, condenser, dryer and hoses. I've seen a lot of ppl put a binary switch in on the dryer. One wire goes to the compressor but cannot find information on what the second wire (off of the binary switch) goes to. It was my understanding the binary switch is the same as the hi-lo switch AND cycling switch. Perhaps these are not all the same and that might be my confusion. Thank you for your input.

The switch is typically in series with the compressor clutch power; in the schematic that would be 14DG.
