Need help reassembling a Super Game Doctor 4M

[untinip]

So I recently bought a used Super Game Doctor 4M:


When I picked it up from its packaging I could hear something rattling inside so I opened it up, and one of the cables/connectors is loose:


If anyone else here owns such a unit, could you please open yours up and tell me which socket to connect the loose cable to? I'd really appreciate it! Thanks!

Check out Ericj's site http://www.famicomdisksystem.com/game-doctor-copiers/ there are pictures of that unit there. There's also a translated manual there.

Thanks, P! Looks like the cable goes into the third socket. I'll give it a try!
