originally i put this under internal hardware, but i guess its more appropriate for it to go here.

ok, i have an old compaq 5610 that i really just want to use the tower to put parts that i have into. i just don't know how i can figure out the power button wires. they are in a harness that they will need to come out of, but then i need to find out how to figure out where they will go. can anyone help with this or point me to a place that can helP?

They might be propriety, but if not, each wire (except for the HDD activity indicators which would be 1-pin) should be 2-pin connections. You should try to be careful and remember, at least, which one is the power button. The rest may not even be needed/necessary. On the different motherboard, the manual should be able to tell you where each connection goes.

Consult your motherboard manual. It should have all the diagrams explaining everything.

ok i have the manual for the new one, so thats not the problem. The problem i have is that the old power button is coming from a 10 year old machine, and each wire does not have a connector, and i can't find a manual for the computer let alone the manual for just the motherboard. I will have to take the wires off of the existing connector and put each pin in their own. The problem i have is how i'm going to identify each wire.

then its doing it the hard way, I had a HP that had wiring harness and I went to put a new build in the case. I had to figure out which wires did what, then used a pair of side cutters to cut the harness apart and then plugged them into the appropriate motherboard pins. the motherboard manual should say which pin goes where, and as far as the harness just follow the wires back and see what they plug into (HDD light, power switch, reset, etc) and go from there.

Well I. CAnt find a manual for the compaq motherboard, and it's not marked on the board since the wires were in a harness. I can't tell what the wires actually go to because they are in a harness that is connected on a board that the button and led's are attatched to. I'll take a picture later. I'm thinking that even if I find a manual for the old mother board it isn't going to contain the info I'm looking for. Anyone have an idea where I might be able to find the manual, I have found the userguide for the computer. But nothing detailed a out the motherboard

Looks like some wires are missing.
Found this...hope it helps.

Red - This is the + power
Orange - This is the - power
Yellow - This is the sleep state LED
Green - This is the active state LED
Blue - This is the HDD activity LED (interchangable with Brown)

According to the images, the wiring is:

Black: Ground - common to all
Green: Power switch
Red: Center LED
Orange: LED furthest from the plug
Blue/(Purple?): LED closest to the plug

If you only want to use the power button ("i just don't know how i can figure out the power button wires"), use black and green.

If you also want to use the LED indicators, since the ground connection is common, it would only work properly and be sure to cause no damage on a motherboard where all the connections are expected to be made to a common ground. That can't be assumed, which is why universal cases have individual connections (2 wires) to all switches/LEDs. If you still want to use the case in this way (ie the mounts suit the motherboard and presumably having no reset switch is OK), and you can't be certain the motherboard references all its connection to ground, then you would need to cut all but one of the ground tracks on that small board and solder on a negative wire to connect each function. (It would probably only be two LED connections you'd need, power and drive activity.)

You dont hav to worry about your old motherboard, you need to find out pins markings on your new motherboard.

In the pictures attached : If you could remove the harness from the PCB and took pictures of both sides we could see which wire is going where.
From these pictures I can guess that Purple is common ground. Green is going to Power Switch and others to the three LEDS.

If you can find the pin markings in your new motherboard, you can attach the wires to them. For example, if you find 2 pin with POWER marking on side, you can attach Purple and Green to them. You will have to use a connector like this:

You will need three extra wires, for other LED's as you will have to attach one cable to the Purple and other to respective LED's wire in the connector.
