Emax

I have an Emax II tthat never had the internal HD. I've decided to
finally do it. I have the case open, and I see the internal power
supply cable, the brackets to screw the drive down to, but I'm not
sure which of the ribbon cables is the appropriate cable to use. Also,
they all seem to have a smaller connector than the SCSI 50 pin
connector on the hard disk. Anyone have any experiences and feedback
for me? 

Many thanks in advance.
