Typical 2mm Drive ID Pin Configuration
Figure 2 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins.

The wires on the wire harness connect to the positive pins (or signal pins) on the disk

drive. In some cases, the drive manufacturer will label the signal pins as Pin 1, 3, 5, and 7

(instead of 0, 1, 2, and 3 as shown in Figure 2 below). Also, in some cases, the even-

numbered Pins 2, 4, and 6, are used for Ground.

Attach the ID select cable to the drive using the 2mm connectors. Align the "ID0" pin with

the black wire. Attach the 1.25mm connector on the other end of the ID select cable to

the 1.25mm connector (J3B) provided on the signal distribution board, located inside the

carrier. Refer to the manufacturer's documentation to disable termination on the drive.


The cables are made up of black, brown, red, orange, and yellow wires.

The black wire is plugged into the ID0 pin, the brown wire into the ID1 pin, the

red wire into the ID2 pin, and the yellow wire into the Drive Activity LED pin.

The orange wire is not used.
