Where do most people route the hoses? Right now the idea is to route them from the right side under the harmonic balancer up to the left engine mount back up to the top of the plenum to the electric boost controller. It seems like it'll work okay in that location but I do want to see what other people have done.
You shouldn't need to run anywhere near the harmonic balancer. I usually put a T up the back of the plenum in the middle and run vacuum lines straight from the wastegates to there. Don't make them too long you don't want silicone or rubber laying across the turbo or manifold.
