hit and miss is how i have done mine generally, 1= pin. ,= blank.
1,,1 = is normally the post speaker. 1,1 is the power L.E.D, and the rest are HDD, HD LED and power and RS. i knwo that nto much help but its best I can do, the power will be 11. with the posotive on the left, (in most cases) posotive will be coloured/negative either black or white
