I'm finally getting around to putting my turbo into my car, but I am not quite sure how I should run all the vacuum lines to operate my various components. I have a boost gauge, RRFPR, and BOV that must all receive a vacuum signal. Currently, my cruise control is removed and my boost gauge is tapped off the passenger side of the intake manifold previously occupied by the cruise. What about the BOV and RRFPR? I would assume that I can tap the vacuum line going to the brake booster for my RRFPR. Can I just tee off the vacuum line for my boost gauge and run an additional line for my BOV?

Thanks,

You can tap the line that the cruise control use to go to.

I have that with a 4 way connector - BOV, FMU, and stock FPR all driven by that.

The boost gauge is tapped off of the line that comes straight up off of the TB.

Where did you retap your cruise into?

Haven't retapped it yet, but probably into that same line.

Anybody else?

DO NOT I repeat DO NOT tap your brake line. the brake line is the one thing you deffinatly don't want to go bad. I had a friend who had a honda turbo swap.. he tapped his break line. at 10 PSI the T- connector that had a Boost Gauge attached popped off. he was doing 140 with "0 psi" and still climbing.. it was bad news when he tried to stop. E-brakeing and downshifting didn't really help but the guard rail certainly did.

I would imagine that it would just kill the brake booster and leave the rest of the braking system alone. However, I will take your word for it and leave that vacuum line alone.

on the 98's the vacume line for the cruise reads on the manifold pres in to one cyl. i used the main line going to the factory map sensor. my mechanic told me there would be a difference between the two gauges, so we hooked up two, and there was like 1 2psi difference, so be careful where ya tap that stuf.
