Electrical Connection Suspended in Space? Picture Included

[TucsonJim]

While attempting to locate the source of a heating issue I identified in a separate post, I ran into the following concern. There is an electrical connection box/faux outlet that is suspended in space behind the cargo panel near the converter. There are screws and lugs on it that indicate it should be mounted somewhere. This doesn't look like normal manufacturing processes to me. This box will be free floating with every bump of the road. Should it be secured somewhere?
