any vac line going into the intake manifold or the one on the wastegate will work, the one on the bpv i dont think will work. but im not sure. i installed one on my friends civic last friday in about 5 minutes, but he has an external wastegate so it was easy i just used that vac line, but it only reads boost and not vac. but ya, any hose coming out of the intake manifold will give u boost preasure. u know that one that goes into ur lower charge pipe? right beside the map sensor, that will work to. cause u got boost pressure and vac there.

my BOV requires a boost and a boost/vacuum source. You can get a boost only from the waste gate actuator. Also i was told you can tap the vac line coming from your TMAP sensor in the cold side piping.

u can actually tap into any vac line that is attached to any part of the intake system after the turbo. all boost reading is is the psi ur turbo is pushing, and any vac line will do as long as it is connected to the charge pipe / intake maifold. u could even weld something into ur charge pipe if u wanted to and attach a line there. its works pretty simply.
