I got confused by your: "The first gen 126 and 82-85 123s used these style of climate control systems."

My 83 and 85 123's climate control system does not have IC's AFAIK. If they do, please let me know which box they are found in. I know my PBU's does not. Are there other 123 climate control boxes with IC's that I am not aware of?
