It also comes through a header and another connector after the fusebox. Connector C0786 and header K109 (C0295). A wire might have pulled out of either of these.
I can't see the header, but the connector I mention is a black 12 way one that sits just behind the ATC (Automatic Temperature Control), not one of the ATC panel connectors itself. My guess is a wire has pulled out of this while you were working on the ATC wiring.
