I am trying to build my first NAS and need help to connect the power SW and the Reset SW.

This is an ASRock B85m Pro4 montherboard. The attached image is what I found in the manual. I put the numbers in red to make it clear.

Both Reset SW and Power SW have 2 wires, one is red and one is blank.

For Power SW, I think I need to use 3 and 4, but not sure which number should be red which number should be black.

For Reset SW, I am lost, not sure if I should use 7 and 8 or 8 and 9. Also not sure which color should go with which number.

    I'm not an EE, but in my experience it's the opposite - black is nearly always ground...

It doesn't matter in this context, since the power and reset switches are just momentary switches that short the pins together. The polarity is only important for the LEDs.
