The 3 cords will fit onto pins at the front edge of the motherboard (probably!). They have to go in certain places and the ones connected to LEDS the right way round. Every computer is different. Hopefully the pins will be labeled (possibly with abbrivations suchas PWR S for power switch. They will hopefully match up to what the cords do.) The most important one for the operation of the computer is the power switch. The others are often useful but not cirtical to the machine working.
