Question about gauge cluster circuit boards

I just went through this. A helpful member suggested to unscrew the thin sheet metal retainer nuts, clean the circuit board contacts and then retighten the nuts. I did that along with the other screws and then it worked fine.
It could be that the 5 pin wire plug isn't seated all the way:

I wonder if the 5-pin plug is the culprit, that seems like something that can loosen up/ be disconnected white installing the dash pad. Thanks!
