Almost (!) always, there are three adjacent sets of two pins, which can be
jumpered to set the SCSI address.  They are often labeled 1,2,4.  These
pins will receive the 5-pin plug (socket, isn't it) assuming that it is a 2x6
IDC connector with one pin missing.  If it is some other arrangement of
pins, like a straight line, then most likely three of them are the 1,2,4 pins,
and one or both of the remaining pins are the common (ground).  You can
probably split the connector (if necessary) to allow it to plug onto the
unit ID pins of the drive.
