The power-good signal is on the orange wire, and is at the edge of one of the
connectors [ hey, there are only 4 possibilities]. It's active-high, you you
need a way to 'yank it down' at will; I would use an SPDT switch as follows:


    (power supply) -------------o
				 \
				  \o-------> to motherboard
   
				o
				|
				v  to ground (black lead)

  The switch is normally connecting power_good to the motherboard; to do a
  reset, momentarily connect the wire to ground.
