here is a good pic at llamma.com
The 5v line is directly under the power supply line. it is also directly connected to the power supply. so the
only way to cut it off is to unplug the power.
the two 12v. lines are below the power supply as well they are beside above the two cylindrical capacitors, but below the single cylindrical capacitor and the wire coil. They are the solder pads where two smd capacitors would go.
I recommemd to use a meter before you solder, just to make sure to get the correct lines. Hope this helps someone.
The 12 volt lines will drop out when power is turned off from xbox.
