Where are the vacuum pipes?

[huwr]

Where about / how many vacuum pipes are there in the engine bay?

I'm currently using the one coming from the throttle body for my dump valve,evc boost controller and boost gauge, I really dont like the look of all the t pieces!

Are any other vacuum pipes that I could use for my HKS evc?

Theres a vacum line from the back of the intake manifold.

I take my boost gauge and boost controller readings from the rear of the intake manifold.The more t pieces youre running, the more likely you are to have a vacum leak, so keep them as direct as possible

try and plumb them into different sources, not all in the same place...and as ragger said, there is quite a few vacum pipes on the inlet mani.
