And I can’t speak for everyone as people have different preferences on where signals should be taken from but my boost controller is tied in between the hotpipe and wastegate.

The nipple isnt on the cold pipe. Now i have my vacuum hose from the wastegate to the controller actuator and then to nothing now. Should i T it into a V line going to the intake manifold?

Also i removed the side mount and there is the vacuum hose that goes to the intake mani and then a tube going to intake piping behind the maf. I blocked off the tube. for the vacuum hose can i link that with the actuator for my controller?
