Configure the drive for remote (external) SCSI ID selection by removing the SCSI ID jumpers (if present) from the referenced SCSI ID pins. Then connect the leads from the external selection switch to the referenced pins. Observe the following guidelines while doing so:

ID bit 0, at Pin 8, is the Least Significant Bit.

SCSI ID bits 0, 1, 2, and 3 (pins 8, 6, 4, and 2, respectively) are active LOW signals. That is, the bit is a 1 if the corresponding remote switch is closed to ground.

Use pins 1, 3, 5 and 7 as the associated ground returns for ID bits 3, 2, 1, and 0, respectively.
