Top Hard Disc Drive Flex Cable for Apple Mac Mini A1347 Server 2nd SSD HDD Upgrade Kit 821-1501-A 821-1347-A (2011-2014) with Tools

Can i use it to install in my macmini2011 an ssd as primary drive and use the old one as secudary drive?

Will it work in a Mac mini 2014 Mgen2ll/a?

On my old hd, I have a small cable that is attached from my motherboard to the back of this unit that plugs into the ssd. Does this have that?

How will I know if it will fit?
