HELP HVAC Control Wiring Identification

[BlairC_789]

1980 chevy malibu. From what I can tell this might be a one year only harness because when I look up harnesses for the HVAC controls none of them have this connector. This is a link to the only one I could find it on OPGI
Two Brown wires (12v) and Yellow wire. It is the one I have circled in red.
What is this for, and where does it plug into?

Also would anyone happen to have a part number or link to the connector I have circled in blue. Thanks.

The red circled connector is for the ambient switch & the blue circled is for the function selector switch. From my GM diagrams that harness should fit all years C60 A/C cars.
