PiCade Hat Wiring diagram

Hi All

I have the old PiCade Hat.

I got the kit from you and it has 10 buttons.

I was trying to use 6 for the controller.

2 at the front for start and reboot. and then 2 for the sound.

But Im a bit confused on where the wiring goes because there doesnt seem to be enough wires.

Is there a wiring diagram online?

As its the old model I keep finding the updated version

Thanks

The pinout is here if that helps


And its GitHub page is here,

As far as the wiring goes, I would think one wire goes from each terminal on the Hat to one terminal on a button. Then the other button terminal goes to ground. All the buttons will have one contact linked together and grounded. Best guess anyway.
