Follow these steps to connect the power supply cable for either a diskette drive or a hard disk drive in the horizontal bay:
1.Looking at the subassembly, locate the power supply cables with clear plastic connectors labelled P1, P2, or P3 that lead from the power supply (behind the horizontal drive bays). (You connect the cables labelled P4 and P5 to the system board later.)
You must connect a power supply cable to each drive you install in your system. You can connect any of these three cables to the new disk drive. One of the cables, usually P1, is already attached to your first diskette drive.
As shown below, the end of the connector has two notched comers. The power supply socket on the back of the drive is next to the ribbon cable connector. The socket also has two notched comers.
