Be careful not to get the small four-wire power supply cable, which is intended for a Zip
drive; the four-wire power cable is connected to the power supply. The audio cable goes
to the motherboard.
The 3-pin audio connector is keyed; so if you have trouble getting it on, try turning it
over. The larger, 4-pin connector should be connected to the four-pin connector on the
motherboard, labeled CD SND INPUT.
The CD SND INPUT connector is near the power supply edge of the motherboard,
above the fan connector and next to the main power supply connector.
