Power Switch rewiring on Power Mac G4

So I'm honestly really confused right now... I'm trying to figure out how to rewire the 10 pin connector so that I can boot up my PC build in the G4 PowerMac however after doing some research of the Pin guide I've found two completely different interpretations of the Pin Layout and I don't know which one is right.

At this point my only goal is to just get the power button to turn on the PC.

Here are the two guides I'm looking at

G4 Quicksilver Switch

Out of Spec

So as you can see they both have very different layouts… which is making it harder to figure out. I don’t know if I’m gonna fry the motherboard if I use the wrong combination of pins.

I've seen one guy use a crimping method from the original wire without any soldering or cutting the board which is what I want to do with my goal however I haven't been able to reach out to him and got any response from him about the wiring.
