    red is always power (or it's supposed to be)
    black is always ground (see above)
    tape off the other green? wire and the aluminum shielding.

    I would strip all the wires and try different combination of each wire until you find the ones that are your power and discard the rest.

    When your using a cd and you cut it, it will generally break. But if you melt the cd lines with a soldering the cd will not break. i will try to make a instructable on how to do it this way but thats when i have time. i will make a hyperlink later on.
