Parts arrived and after looking at that new wiring harness, it's, unfortunately, not what's needed. This is a HVAC harness, but I suspect the harness that connects the sun sensor, cabin temperature and C2 on the HVAC module is part of the 'Body' Wiring harness, rather than part of the HVAC harness. The trial failed...the part is being returned. We're now stuck...Part ordered. I’ll try it out this weekend.
