You can connect either the AC’97 or the HDA connector, depending on your motherboard.
Locate the internal audio connectors from your motherboard or sound card and connect
the corresponding audio cable. Consult your motherboard or sound card manual for the
pin‐out positions. Even if your system supports both standards, only use one connector.

Connected to your front panel are LED and switch leads for power,
reset, and HDD LED activity. Attach these to the corresponding
connectors on your motherboard. Consult your motherboard
manual for specific pin header locations. For LEDs, colored wires
are positive ( + ). White or black wires are negative ( – ). If the LED
does not light up when the system is powered on, try reversing the
connection. For more information on connecting LEDs to your
motherboard, see your motherboard manual.
Note: Polarity (positive and negative) does not matter for
switches.
