Yes, that'* where the solar intensity sensor goes. Since you say you don't have the electronic controls for the A/C, I'm wondering whether you really have anything inside that, though...?
The dome over the sensor is actually a deeply translucent color that you can actually see through in strong light. If yours is definitely black, opaque, then I'd sayit might just be a filler (although I dunno why they wouldn't just put a flat plug in the hole).
