    Just wanted to say thanks very much for this guide. Power on/off works perfectly and I have a glowing LED. Reset isn't doing anything, but I've probably wired something wrong. Your graphics and explanation were a lifesaver!

    This was a big help! I'm really glad someone took the time to do this. I have a curious question, though. I have a Sawtooth front panel and ribbon cable that I spliced according to the pinout in Post #1, and all the switches work, but oddly the Power LED is on all the time, even when the computer is off. It's a small thing, but I'm wondering why that would be?

    I'm running a Gigabyte GA-H170M-DSH3, and the one change I made (accidentally) was wiring the PLED + to pin 10 instead of 9, giving me the yellow light.

    Anybody have any ideas why the light is on all the time?
