How do i plug in power button in on mother board?

How do i plug in power button in on mother board? Lost my manual so I can't find the model #. I was just switching my mother board and all other hardware to new case and my power button (or switch or whatever its called..the button you press to turn comp on) used to be a one plug in but the new tower has 5 different ones....power led, H.D.D led, reset sw, s/b sw, and speaker. Need to know where they go!!! help please!!

If its any help i think the serial # is 605 6628452691
Also the number on what i think is the printer port is 001617761c21

Thanks for any help
