Hi NCMN, it could be that the motherboard requires a header connector with three pin spaces, the middle pin will either be un-populated or ground (black), like this example.

You might be able to remove the header on the switch lead and attach two individual header connectors (Dupont Single Pin Connectors).

I've done this in the past with fan headers and case headers which were not compatible with the motherboard I/O pins.

In my experience as well when the turbo light is on it means the higher MHz setting is engaged eg. Turbo on 66mhz / Turbo off 33mhz, also changing the turbo setting using the switch just signals the board to change the CPU clock on a full reboot cycle, it's not realtime.

Hope this helps, W.

Thanks for the reply Whiskey! I went home last night and tried working on this some more. I made a three pin jumper to connect pins 15 and 17 to simulate a three pin switch, but nothing changed. I also retried jumpering pins 15 & 16 and pins 16 & 17 and restarting the computer with each jumper changes, but still didn't have any luck. I may just give up on it. I previously went to the effort to add a switch to the front of my case to act as a turbo button, so I would have liked for this to work, but in reality it would rarely, if ever, be used.
