Case speaker pinout

[dieselmb]

This may seem dumb, but I am unsure of which pins to connect for my
case speaker.
The speaker has 2 wires in a 4-pin connector (red - NC - NC - black).
The MoBo has a 4 pin header: Speaker - NC - Ground - +5V.
NC = No Connection. Which ones to use?

You only have two connections to make if you take out the no connection
point. Normally, red goes to positive and black to ground.
