Hey Dave,
I see what is the issue. This first picture is a normal non a/c wiring setup. The dash harness has an insertion wiring connection between C1-14BK* and C1A-14BK*.
For the A/C wiring, disconnect C1-14BK* and C1A-14BK*. The A/C sub harness dual tan connector C7-14T and C7A-14T plugs into C1A-14BK*.
Further away from the A/C controls, there is the CIC-14BK* on the A/C sub harness that plugs into C1-14BK*
I edited the schematics to show where these connections are.
Hope that helps.
Jim
