You're right - the PLED lead in the Antec P160 case comes with a 2-pin
connector (probably a manufacturing error) while the motherboard needs a
3-pin connector with an empty middle pin.
My P160 came this way as well. I solved it by using a needle to carefully
work the ground lead (white) out of the 2-pin connector. Then I took one
of the 1-pin connectors from the firewire cable, which I'm not using, and
removed the plastic connector cover from the lead. I placed the white
ground lead into this single pin connector.
Then I attached the 2-pin connector (which now only has the green + lead
in it) to the motherboard connector, and attached the 1-pin connector
(which has the white - lead in it) right next to it.
Works like a charm.
Good luck with yours.
