Do you happen to have the Documentation that came with the board? If so, then it should have the placement of the connectors, plus you will also need to know which connector of your case goes where, thus either the connectors have to have it written on the socket itself or then you need the case's documentation too, or you'll need to trace each case connector to it's end point to know which is the power switch, reset button, hdd led, power led, speaker.
Also you'll need a flash light and a magnifying glass
to see if the FP connector pins on the Mobo have their designations written right under them, they usually are.
Check and let us know.
