I got a hold of 2 diagrams for the 1982 Olds Cutlass Supreme with a V6 2 barrel carb. 1st is a vacuum diagram for hooking up the A/C and heater control correctly. Mine got stuck in default mode and has been nagging me since I want the vents working. 2nd is an engine vacuum diagram. Again, this is for the 231 V6. This is for Cali emissions, not to sure if that would make a difference.
P.S. I think the A/C one might work on other vehicles. Not to sure.
