3pin case power switch with 2 pin mb header

[sdadept]

I bought a habey 2u case that has a power switch line with a 3 slot pin female end. The motherboard I have (supermicro x7dbe) has a 2 pin male header. Anyone have any idea what I need to do to make these two talk? googling 3 pin to 2 pin brings up a ton of noise but nothing I can use.

If it's anything like some of the lian li connectors, you can take something like a sharp knife, lift the black tab for the wire you want to move, and pull the wire out and move it over a slot. That's what I did with my current case/mobo.
