It all depends on the motherboard.  They are in all kinds of different places on different manufacturers.  They are usually color coded.

Written somewhere on the motherboard is the make and model of it.  If you can find that, I might be able to find out.  Just need a little more info.

Usually the speaker is red and black and it 4 pins wide, the reset switch is 3 pins wide, the power switch, power led, and hdd led (if avail) will all be 2 pins.

Carrying on from ryan_johnston's comment.

Look for a series of letters and numbers.  That'll be the motherboard model number which you can Google and find the manufacturer's manual.

Also see http://www.formfactors.org/developer%5Cspecs%5CA2928604.pdf and pages 17 and 18 which might be of use if the board uses standard Intel connectors.

It doesn't matter about the numbers in the pictures. Thats just telling you which pins are what.  Just put the cables on the the writing facing out.

ok , but what I gt is like this power sw(red/white )2 pins , reset sw (obagine/white) 2 pins , h.d.d led(black /red) 2 pins and then one white & green cable with one pin each , so I gt total 8 but in the pic it should be 9 !!! is there a way to gt the manual pls
link

hnael

In the picture I showed you...you don't need pin 9.  Hell, you don't even need any of them plugged in except the power switch. If you have just the power switch plugged in and nothing else, it would still turn on.

I'm not getting frustrated, just saying that those aren't a huge deal to where if you plug the wrong one in, thats it's going to fry your computer.  It simply won't work, then you try again, and repeat til it works.  If it doesn't work and they are plugged in properly then you may have an additional hardware issue such as a bad Power Supply or bad Motherboard, etc.

As long as you get the right pair of wires to the right pair of pins there is no problem.

For example you can get the power switch wires around the wrong way and it will still work.  White is usually the ground wire.

You've got two LED connections there.  If the lights don't work then reverse the connection and they should then then work.  Being round the wrong way won't harm them.

But just get the right pair to the right pins and you'll be OK.
