It's not a ground.
If ground is present in power connector pin, then usually case is grounded too. Even if they are not connected, radio would work (not talking about reception). So your problem probably is not related to grounding.
If you really want, you can just slam some bare wire between case panels and ground it for testing.
Post#14 shows it is some coax cable, so probably power or signal for antenna etc.
