You need a three pin high pressure sensor. 47 goes to the AC command from our HVAC, you can splice it in with the low pressure sensor on the filter dryer.

Technically either works. If you use the blue you are still utilizing the cycling switch which is what is recommended. If for some reason you don't want to do that the green would send the AC command straight from the HVAC controls.
