This sounds like the power connector. Your external case should have a
corresponding plug that fits this connector on the CDR drive.

This is where you configure the parameters for the CDR, including its
SCSI ID number. Jumpering the first two pins, (upper/lower pair, labeled
'1'), gives an ID of '1'. Jumpering only the second set of pins,
(upper/lower pair, labeled '2'), will give you an ID of '2'. Jumpering
BOTH the first set and the second set of pins will give you an ID of '3'
because you're now 'adding' 1+2. Removing those and jumpering only the
third set of pins (labeled '4') will give you a SCSI ID of '4'. SCSI ID
'5' is achieved by jumpering '1' and '4', while '6' is achieved by
jumpering '2' and '4'. SCSI ID '7' is normally reserved for the
controller, I believe.
