G5 case Power Button

[digieditny]

Hello all! My power button is working. I push it and the computer boots up without issue. The problem is when (once in a blue moon) I crash and I have to hold the power button to force shutdown the computer, it doesn't work. Holding down the button does nothing. I'm using "G5 Front I/O to ATX" Cable from AlohaCab. I use to have this working. I know I had to connect one of the cables to the motherboard but I can't remember where on the motherboard. The computer was moved and the cable detached from where I placed it. Yep, my fault

I'm racking my brain to get this working again... Any clues?

Which cable came unplugged?
