Illuminated tracball power??

[numbnutz48]

I have an illuminated tracball from HAPPS. I'm no electrician and i don't wanna screw it up. Where and how do i get power to make my light work? There are 2 terminals for the light, does it matter which is +/-?

If it's a 12v bulb, just take power from a molex connect off your PC power supply. The yellow wire and a black wire (either black wire).
With an incandescent bulb, it doesn't matter which wires go to + and -.
