Color Code help

[nymph4]

I am huckinh up my Power Button from my Power Switch to my Motherboard.

I know that whenever I see a Plug with a Red and Black wire  say the Power Switch  the Red = Positive and the Black =  Negitive.

But my Hard Drive Led Plug has a White and Blue wire  and the Reset Plug has a like a Red and White.

Can you help
Witch one are negitive and Positive when it comes to Plugs with White and Blue wires

Look for a small triangle embedded on the wire lead connectors to position the motherboard connector pins correctly...Look for pin1 to be labeled on the motherboard as a small "1" embedded either to  the left or right of the group of pins....Guessing is OK when connecting a wire to a connection......if it doesn't work no harm is done.......You can also get this info from the motherboard documentation.
