How to Modify Fetrotech Tool Silver to Work Alone as Black?

Possible to use fetrotech tool silver indentpendly without pcmtuner? One of fetrotech users found a way. 

*You are at your own risk. 

The Fetrotech tool silver works with pcmtuner because PCMtuner has a bridge at this point. It works on the same software, the difference is in the bridge.

Took apart both black and silver board and found the difference.

if you want your silver fetrotech to work alone. then do a little modification. that is the difference between black and silver. much more comfortable work.
