Building old pc into new case

[Buildinghero Gaming]

I have a problem. I found a pc case next to a neighbours garbage and it's actually really good so I was gonna use it. It has the regular reset power and hdd light switches but on my motherboard there isn't those plugs. Instead there is one 7 pin connecter wich in the old case I just plugged in and it worked. First I thought it just wasn't possible but then someone built a Windows 98 machine into a brand new case and I was confused. Is there like a special way I can plug the power reset and hdd light plugs in so it works?

maybe some adapter? seen div to hdmi, so must be an adapter for most things. find out what the case vs your board have and the equivalent for the port name?

That's what I thought too but I couldnt find any information about the change of that standard

Look at your motherboards manual, you can put the 2 pin cables on the corresponding pins.

@Buildinghero Gaming What is the model of your system/motherboard?

I'm using a motherboard that I picked up from the flee market. I looked up the order in which to connect the pins and it gave me a plan of wich to put where
