Step 4The power button and power light
For the case power button and power light, I had to junk all of the circuitry on the associated board. I tried testing the output pins with my multimeter, but didn't have any luck. I figured it must convert everything over to digital before sending it to the logic board.
I ended up just haphazardly scratching a break into all the old pathways. It didn't have to be pretty, since the board would be hidden.
I then soldered wire from the connector to the components I would use (power button, reset buttons and power LED).
Now, to actually get the signal to the motherboard I needed to get from the original ribbon cable to something that could actually connect to my motherboard. I desoldered the old connector from the original logic board, then soldered some scavanged wires/connectors to the backside. That way I could just plug in as I normally would.
The best way to get an understanding of this is to check out the pictures.

How did you figure out which connection was positive or negative?
