Ok i inatalled my ARC front mount and BOV today, however i have a problem, the car is running rough( engine is shaking alot) i am guessing the problem is something with the vacum hoses somewhere. i got 2 hoses that i am not sure where to hook up to. one that is comeing from under the TB does it go to the BOV or to intercooler also there is one on the driver's side i am thinking it is coming somewhere by the turbo, dunno where that goes either. i have a s15 sr in case that helps. any help would be apreciated. thanks in advance.

Bottom of the TB goes to nothing it should be blocked. The two top nipples should go to anything that needs vacum source. The big pipe be the TB is IAC it should be self exsplanitory.

Vacum Sources I can think ofFuel Pressure RegulatorBOVWastegateBoost gauge (if you have one)

if i block the one that goes beneath the TB that leave the one on the wastegate. then i have two places for that to go one is to the BOV and then there is one that goes intercooler piping that one that goes to the TB. which one is the vacum hose from the wastegate is going to go to? i am gonna take some pictures to try and make it more easier. thanks

Small port on top of the TB goes to your FPR,Boost gauge.Large port goes to your BOV..Port on the bottom of the TB is not used so block it off..Wastegate goes to that port on you intercooler piping coldpipe..The one you have going to the port on the bottom of the TB..
