I am doing some research to make my turbo install next month go smoother and am wondering if anyone can show me what vacuum line I should tap into so I can run a vacuum block for my other stuff. There's quite a few similiar looking lines back there and I can see a few near the throttle body too.

 

The instructions with the Dezod kit say to tee into the break booster for the vacuum manifold. Then everything (BOV, wastegate, FIC, boost gauge) is run off that. However, I'm having some problems right now that may be vacuum related - as in not enough vacuum - so I'm planning to tee into the break booster separately for both the BOV and wastegate. Only the FIC and boost guage will be connected to the vacuum manifold. Hopefully I'll get that done this weekend if the clamps I ordered arrive. In the meantime, I'm driving it like I used to drive my '87 Plymouth Horizon - slowly and no boost.
