On the U - Intrusion Switch Connector?
I believe the style of switch used, is if it is open, then the computer will not work.
Therefore connect a small wire to those two pins.
(Same thing as the switch is Closed)
Need Molex female metal terminals?http://www.molex.com/molex/products/datasheet.jsp?part=active/0002081202_CRIMP_TERMINALS.xml&channel=Products&Lang=en-US
Could I be wrong about how the switch works? Yes.
Could be the alternate style where the switch is open, and removing the computer case cover, closes it.
In this case do not connect a jumper wire.
All the other wiring connections are shown.
Have a specific question on the wiring? Post back in a Comment.
