Vacuum lines connections

Hi, Im in the process of installing my turbo and have a couple questions.
I use MSPNP.
First, the MS vacuum line is connected to the cruise control vacuum.
Now, I also have a BOV and my boost gauge. They need a vacuum fitting.
Should I just tap the intake and add 2 more fittings for each one or just connect MS, BOV and boost gauge to the cruise control niple?
Are there any other sources from which I could use a T fitting to connect the BOV and gauge?
Thanks

The best place for you to tap into your intake manifold for the MSPNP will be in the middle. The cruise port is noisy and can cause problems in your tuning. You can cut the line going to the fuel pressure regulator and T off of it for the MSPNP. Then you could T off of the cruise port for the BOV and Boost gauge.
What would be a great solid solution would be to add a vacuum manifold to the brake booster line. It would give you a great signal for all three items, or just the Boost gauge and MSPNP. Then tap the cruise port for the BOV.
If you're using a Tial BOV the cruise port will be too small.
You can get a vac manifold here: http://tunertoys.zoovy.com/c=pTlqE42...s_Edition.html
Or go to homedepot and make your own.
I tapped my manifold for two extra ports and am only using one.

I'm not sure if it would cause problems, but the black anodized one that you linked to is not rated for vacuum. McMaster states in the description that only the nickel-plated or steel versions are vacuum rated. I'm not sure exactly what would prevent the others from functioning properly under vacuum, but it is stated in the description nonetheless. Any thoughts?
