Took this a step further, no splicing of wires, no soldering, just used jumper cables, matched them up (based on your pin ID, tsk) to the front panel connector and mobo pins (specific to my mobo) as well as the speaker.

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?

I don't get it. If you can just use jumper cables and you can get those cheap then why would anybody ever solder anything? Isn't using jumper cables so much more convenient? Would that work with QuickSilver or G3 b&w front boards too?
