Dell Optiplex GX270 Board 0U1325 power button pins

Solution

I just finished figuring out how to do this, and I rang out a bunch more of the wiring than was previously posted.

here's a diagram of the connector on the motherboard:

33 31 29 27 25 23 21 19 17 15 13 11 9 7 5 3 1
o o o o o o x o o o o o o o o o o

34 32 30 28 26 24 22 20 18 16 14 12 10 8 6 4 2

The 34-pin ribbon cable runs to a small sub-board for the front panel, which includes a 16-pin(2x8) header which gets another ribbon cable that goes to the "sub-sub-baord" for the actual poanel light and switches.

The table below shows the functions of the pins on the 34-pin connector, plus where they connect to on the 16-pin "sub-board" header.
