id like to know the pinout, or the wiring diagram(basically what color wire represents what function, as far as grounding and led lighting, im looking to use this for a raspberry pi project as far as a on/off button with led function. Any and all help with this is appreciated, i can post links to board for reference if ok within site permissions, being honest i glanced, but you could message me about board. again just need to know what does what ass far as wiring, google seems to be useless for this info. As far as i have searched anyway

What is the exact model name and number of the motherboard? Each board can have a different pin configuration.

Right. But you need to connect those to the motherboard. That's where the pins are. Without knowing EXACTLY which board you have, then it can only be guess work, Although many manufacturers tend to use the same pinout on most of their boards.

this is the motherboard, ill try to get a pic of board where wires lead out, but from the front of the board i linked in previous post, the wires go yellow, orange, red, brown, black. left to right. need to know what powers board and the functions of other wires for LEDs. I cant find anything on google for the motherboard, or the pc power button board(which is all i need) any where, no diagrams or schematics that pertain to parts. But before i forget, thank you for your help, it is very much appreciated.

Well, this may help you. It turns out that there is a standard after all. So here's the pin out. One caveat though. I couldn't find anything specific to that board. But this should be the "standard" pin out for those connectors.

there is more to it, 5 LEDS, aside from the button, which is in perfect size and formation for my project, and the only thing holding my project up, which is why im trying to figure out this little board, but the saying to good to be true is fastly becoming my reality for this little board is apparently the needle in the haystack.

Do you have the "old" connector and cable? If so it should be fairly simple to replicate the setup. If you look at the motherboard it looks like the connector is a 10 pin white one.

I just looked again and it could be that 5 of them aren't really there. Could be the angle of the pic that made me think there were 10.

Have you tried to get a hold of Gateway Support? I actually don't know if they still have a support #

Here is a better image of the plug, my bad for angle on last one. I'll have to wait till after xmas to try to call, if that's an option anyway. I was hoping to finish this before xmas tho. Present for someone. I think I'm gonna risk some breadboard experiments and hope for the best. I'm not giving up, gonna find a way to make this work. Again thank you guys for the help. Hopefully one of us can help nail this thing down, be an awesome button for Raspberry Pi projects.

P.S.
What do you mean by old connector? I should note its from a gateway all in one computer that had a busted screen so i have been recycling parts, this is the little power button from the front of the pc, the LEDs functioned for off/standby, then on, then also hdd activity, I pulled it from the computer for the raspberry pi

Ok. So how does the other end of the cable look like? Does that connect to that "mini" board that you previously showed?

And if it was pulled, by you, from a different system? THen you should know how to reconnect it.

Again I pulled the part from a PC. I'm going to use it on a raspberry pi. Totally different pin layouts from pc to a raspberry pi. Im cutting the end of the cable off to solder connections for pins to plug to the pi. Having trouble finding out the circuit path of little power button board I pulled with LEDs. But, I've made some progress with tinkering. Pics will show I got orange power/standby lights, white on lights, and the switch works to turn on string of lights. Sorry about the chicken scratch notes, thought they could help.

The thing is that part was designed to work with a particular motherboard and would interact with the circuitry on that motherboard which you would have to duplicate.
