98 Ls1 PCM pinout to kee A/C?
Do i leave all ac wires in tact to sensors except pin 47 AC REQUEST SIGNAL. im guessing that gets wired to factory hvac a/c wire?
will any sensors need to be cut or spliced with 3rd gen sensors?

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.
