Keyboard ZIF Connector Pinout

I'm looking to determine which contact on the keyboard connection on the A1342 is for the 'on' switch function (or any other contacts on the logic board will do). I'm fairly certain this pin is active low (pressed goes to ground), yes?

Thanks, Keith

It boggles my mind that this little picture was so hard to find on the INTERNET it is almost like these companies making laptop er um notebooks these days dont want us knowing how they work or operate.

That way we cannot ever comprehend enough to troubleshoot or fix them when something goes wrong. Or they just dont want us realizing that they are built to fail in so many hours. Grrrrrr
