Uhh.. How about telling us what this "vaccum box" you got would be? Who made it, what does it look like, does it quack?

soo... its a golden eagle.. made by gold eagle.. i plugged all my vacuum lines into it.. and would not hit vtec, or boost... unplugged bov, and 3 bar map sensor.. re-routed those to the back of the manifold... and bam.. it hit vtec, and boost.. but i thought this things were suppose to allow you to connect all vacuum lines into it.. ?? thanks again

that is the only way to hook it up "i believe" the check valve only lets air in when the brakes are applied, if you used the line between the BB and the Check valve your screwed...just turn on the car and see if their is suction...it should be connected to the vacuum line in between the IM and check valve...or whatever that valve is called
