I had to replace my bypass valve due to human error, and I've had the blower apart long enough to forget where took hook in the air line to the bypass. Does it attach to the back of the j tube, or does it attached to the top of the manifold near where the stock map sensor goes?

 

Connect it to manifold vacuum. The factory connects it to the back of the J-tube. There are 3 ports there, and mine is hooked to the one farthest to the right(passenger side).

 

Ok, thanks. I was going to hook it up to the manifold so it would see boost and vacumm.
