Wastegate Vacume

[Go_the_mini]

Quick question, have put the new wastegate in and welded up turbo, screamer pipe is on an ready to go just need to sort out the last of my vacume lines. Can anyone tell me where the two vacume lines from the wastegate run? Guessing one must go to the vacume on the top of the turbo that used to run to the actuator, Cheers any sugestions are much apreciated.

For external use bottom one for boost reference and leave top one disconnected. Do not block the top one. Top one is used when you have electronic boost controller.

my suggestion
plumb the "screamer pipe" into your exhaust or run it through a muffler.

"boost reference" Would that be the hose running off the top of the turbo? Sorry for dumb questions, first turbo car
