The adapters at the bottom look like the selection that comes with some return pumps and not the tanks itself. I don't see any plumbing for the return or the e drain. Not sure if the piping in the overflow is there or not. I found this diagram that may help determine what is missing.

If you can't get help from the seller, and the diagram doesn't help I would suggest looking for some aquarium service company to help you get it set back up.
 
Op did you check all the seams good before you handed over your hard earned cold cash. Before you get too far into this. 😅
