    Hey can anyone tell me where the 3 hoses go to and from the N75 valve on a 1997 Jetta? The sticker just shows lines going to it but it's not clear. There is a L type fitting on the bottom one pointing forward and one down and one line out the top. One is to the intake hose one to the wastegate and one to the pipe by the turbo. My hoses have no color on them. Any help is appreciated. Thank you.

    Definitely not. N75 is connected to the pressure control loop, this means the actuator (VTG or Wastegate), charge pressure, and ambient (wastegate chargers), or vacuum (VTG chargers).
    Cheers

I just need to know which goes where?:annoyed love when the youngins (kids) start grabbing at stuff and taking trash (tape) out of from under the hood. lol I guess I'm taking pictures and puting colored paint on stuff from now on.

    Thanks all.
