Russian small stone wiring diagram??

[burnt fingers]

Hey guys,

I searched but did not find what I was looking for.  I need a wiring diagram for a russian small stone.  The one over at GGG is not the same as the pedal I have here. 

My friend asked me to replace the switch with a 3pdt so he can have true bypass and keep the led.  The problem is,  There are about a dozen white wires going to various points on the circuit board.  Nothing on the board is marked so which on is which is a struggle.  Even tracing the wires is difficult because they are mostly stuck together somwhat like ribbon cable.

Any help would be appreciated.

Please!!!....

Don't make me have to trace 11 white wires to an unlabeled circuit board.  I don't speak Russian and I'm sure I can't think like a russuan circut board designer.
