The line doesn't run to a wastegate, it runs to the wastegate control solenoid. I apparently do not have these as there is nothing mounted to the bracket shown in the diagram from the mechanics manual.
Do you delete the control solenoids when you put a manual or electronic boost controller in therefore bypassing the need to have a vacuum line run from the nipple I originally asked about?
Sorry for all these questions, I'm just trying to fix this and have it not leak for at least 6 months lmao.
