motherboard pin connection (power sw,etc)

The header is somewhere in the bottom right corner of your motherboard ... in the picture, it's under the video card  and somewhere below that heatsink which has ASRock written on it. 

 

The headers are pretty much standardized, should be the same pinout as on other motherboards from Asrock, so you can use the manual linked above to inspire yourself

 

For example from page 15 :

and page 29 zoooms it out :

LEDs  care about polarity - if you insert it the wrong way, nothing bad will happen, but the led won't light up. So you can just turn off the PC and flip the connector so that the wires are the other way around. But traditionally, plugs should be inserted with the text on the outside, if there's any label or something printed on the plug. 

 

The button / switches (power switch , reset switch)  don't care about polarity , it's a momentary buttons, you connect the two pins together when you press button. So it doesn't matter which way you put the connector in. 

 

Don't forget to connect the power to your video card and your CPU and don't forget to make the absolute noob mistake of not having spacers between the case and motherboard (most cases have spacers pre-applied - the motherboard bottom should not touch the case, and spacers should only be under motherboard screw holes.

Hey! i just bought a new gaming computer from a buddy to keep around and it has a (asrock b460 pro4s/ac) and the pins came unplugged so i looked up the motherboard manual for where the pins go because its very difficult to tell on the motherboard itself, but every manual i have seen has been wrong ive double checked a millions times and i just cant seem to figure it out i know its not the case because my audio and usbs will work. If anyone can find the correct location for the pins that would be awesome im currently using a screwdriver to power up my pc lol thank you!

Unless this isn't your motherboard, this manual should tell you where all the pins and headers are: https://download.asrock.com/Manual/B460M Pro4ac.pdf

sadly this is the original one i looked at, it is not the same as the one i have idk why but i cant even find the motherboard itself online the motherboard on the right side says asrock b460 pro4s/ac i thought maybe the one you linked could have been the same but the io is different this was a prebuilt originally so idk if that can have anything to do with the type of mb 

 

it is a b460m PRO4S/ac

Apparently the asrock b460 pro4s/ac is just a System Integrator (iBuyPower, CyberPC, et al) version of the asrock b460 pro4/ac without VRM headsinks and some minor changes. In fact, the board model is likely just a sticker with the old non-S board model underneath. 

 

This very bottom right one is your switch headers:

I'm still looking for a high-res enough to confirm the pin-out
