1. Locate the diskette drive ribbon cable. One end of the cable is
connected to the system board. If you are installing a
second diskette drive in the lower horizontal drive bay, the
other end of the cable is connected to the top diskette drive;
use the middle connector. If you are installing a diskette
drive in the upper bay, use the free end connector.
The diskette drive connector that extends from the back of the
drive has gold contacts on both sides. Grasp the cable
connector and align it with the drive connector so that the
key-way (the plastic divider) in the cable connector lines up
with the gap in the drive connector, as shown below.

Make sure the cable connector fits properly onto the drive

If you do not align the connector correctly, you could
severely damage your drive when you push it in.
