Where do vac lines go?

[L18M]

where do the vac lines from the wastegate go to?
one to the boost controller, and thinner one to nipple on uim? (under bac)

boost gauge goes to nipple on uim (under bac)

map sensor to nipple on uim (under bac)

thats how mine is pluged in. any reason why the boost gauge does not work when it did before?

thinking maybe i pinched the boost gauge vac pipe somewhere but then the needle should still move a bit as not easy to completely cut 100% air off.

thx thx

Sounds like a good place to start. Or maybe the pipe has come off the back of the gauge.
I\'ve got mine set up like yours but since I\'ve changed various bits I have more places to get Vac sources from so at some point I\'ll spread the hoses out so they don\'t all get the same supply.
