your motherboard manual should have the info you need. you probalby got that pic from your manual but they should have which one is which. generally the colored wire it the positive one. what motherboard do you have? btw for everyone else I did scan the pics and they are clean.
I really dont think you could screw anything up buy hooking them up wrong. One time I took the power switch one and just kept trying different pins until I got the right ones.
White wires are negative, colored are positive... Reset switch might be both grey... if so then just match up the text with the rest of the wires... you'll know what I mean when you've got em plugged in.
