    Google "PC PSU Pinout", or just ground the green wire.

    Go with the green and ground, black wire any molex black or the 24 pin sockets black.
    If it fails to start use a 10 ohm 10 watt resistor or a 10 or 20 watt lamp on the 5 volts rail red +black, there may be sense wires pink is common as is orange, but these are normally spliced together in the plugs, so should fire up ok, if its running and not blown that is. Dave. :)
