Jason -

The 4-pin peripheral connectors coming off your computer's power supply
carry +5v(red) and +12v(yellow) and two grounds(black). The easiest way to
tap the power is to cut a matching male molex connector off of something
sacrificial [like a molex-to-floppy adapter, a molex y-adapter, or an old
case fan] and splice longer wires to the connections you need; or if you're
more of a perfectionist and can find the parts you could crimp your own
molex connector together...I just don't recommend cutting or tapping
directly into your power supply.
