connecting case wires to mobo

Specs: none yet, none yet
my new case is badly documented and does not explain how to plug the power and reset button cords into the motherboard. I expected there to be a diagram. The only clue is that each pair of wires has an arrow on one of the pins. These are the wires:

H.D.D led (2 wires)
Power on led (2 wires marked as + and -)
Power switch (2 wires)
Reset Switch (2 wires)

they all have one colored wire and one white wire except the reset switch which has 2 similar colored wires. The arrows are on the colored wires. Also it says KSP by the arrows. How do I plug these in?

Its no the case documentation you need, its the documentation of the motherboard. You have all the information you need as far as the case is concerned. Now you need to know where to plug them in on the motherboard and your motherboard manual will tell you that.

Its no good supplying a diagram with the case as the motherboards it plugs into are all different.

The power and reset switch wires don't really need to be marked +/- because it does not matter which way you plug them in on the board. But with the LED's it does matter. When you located the proper plugs on the board, you should see them marked +/-. Make sure you get this right or the LED's won't function.

"each pair of wires has an arrow on one of the pins"

The wire at the arrow is the + lead.

Yes, you need the docs for the motherboard. If it's something besides Amptron, ECS, or PC chips, you can probably download the info from the 'net.

+/- will not damage the LED's, they simply will not function 'till you turn them around. I just hook them up, and if they work, fine. If not, turn them around.

"You have all the information you need as far as the case is concerned"

I have no idea what each wire is from the case. I know which pair of wires are supposed to be for the pwr button, reset button, and the leds - but the case documentation says nothing about, for instance, which of the hdd led wires attaches to VCC5 and which of the hdd led wires connects to HDDLED on the motherboard.

I have the documentation for the motherboard and I had already looked at the diagrams for where you plug in the cords. The problem is that in the mobo documentation it says :


So I know what the pins are on the motherboard but I dont know what wires to connect to what pins. That is what I meant by saying the case should have better documentation. They should have a diagram saying something like for the hdd led the blue wire goes to VCC5 and the white wire attached to it goes to HDDLED.

So since the arrow means positive can I assume that means that where the mobo documentation says VCC5 that means positive and that HDDLED and PWRLED mean the negative connection? The mobo says nothing on it about + or - but I assume that gnd is negative and VCC5 is positive. I will try it both ways since you say it cant hurt anything. Thank you for the usefull information badboy, blackbill and name.

AS far as the LEDs go, as already stated. Just plug them in. If they are the wrong way round and the LEDs don't light, reverse them.

With the Power button and Reset button, it doesn't matter which way you plug them in.

The case documentation doesn't tell you anything about the motherboard because every motherboard is different, different even in terminology that describe the connection.
