Here is a link for a DIY I did
for another site. The photos do not work that I put there, and not able to fix, but all the info that I went through and part numbers are there. Good luck.
Ours works like a champ. Best thing for the compressor is to run you a big gage wire back to it with a relay. My small gage with the AS put in was getting hot, and when I went to the new system, compressor runs much faster!
