Messed around a little with the factory switch today and I got it working! Here is the pin-out order.
If you're looking at the switch from the backside (label up) the pins are from left to right:
1) illumination (red)
2) common ground (white)
3) signal (continuity) to trunk (black)
In the meantime, I used small female pins from a donor PC case ( the small pins from the power switch, motherboard speaker, etc. once I find the actual male harness from mouser, I'll update it here.
