Diagram 2: Simply plug the connector onto the header/pin-out, in such that; black wire is connected to MIC pin, red wire to MICPWR pin and the GND wire to GND pin.
connection guide
If the 3 active pins are not located in one same row (refer to diagram above), you need to change the header connector, and rearrange the wires to match with the pin assignments.
NC pin (no connection - empty) is not a GND pin. Do not connect the GND wire to NC pin.

You can connect CPX093-2 to the IFPA / AC97 header by purchasing an additional 1x3 header connector, and rearrange the wires in such that; black wire is connected to MIC pin, red wire to MIC PWR pin and the GND wire to GND pin. Do not remove the Line-Out jumpers so that your onboard rear speaker socket will remain functional. Part of the 1x3 header connectors can be left overhang outside the pinouts.
