Well guys :)
Soon I\'ll go to single turbo,
I would know, if is necessary modify the stock harness for it?
I can exclude the solenoids whitout modify the stock wiring?
Yeah, all solenoids can be removed although i would advise you remove the harness and re-wrap it and remove any redundant wires whilst you\'re at it. At the same time, you can remove all the metal vacuum piping in the engine.
