Hi & Welcome... 

[arkham]

thanks dude

[arkham]

it s work and not, the true bypasse don t work, but the effecct yes, and i think it s coming for the schema cause it s not the good

my wah is the version of 1997 , i put the schem here  if you have a solution

Can't see any difference on IN-OUT wiring fορ both schematics..

If effect works, it means you've wired correctly IN, OUT & GND so check for proper IN & OUT sleeves grounding in by-pass mode..
(I presume you use stereo plugs - at least, for INPUT..)

P.S.
Forgot to tell you about LED- red wire on the lower left side of 3PDT switch which corresponds to status indicator LED cathode and has nothing to do with any other LED appearing on schematics..
