Dump Valve Fitting

Hi, just got my first 180sx, got a second hand dump valve ready to fit but i am unsure where to connect the small vacum line into to operate the valve? Also how close to the inley chamber to go ? Does it matter?

Thanks for any help/pictures

Assumptions: it has a CA or SR, your talking about a blow off valve, and the inlet chamber is the Intake Manifold.

The Dump Valve on 240s is usually put on the Hot side (Pipe from turbo) the Vacuum line needs to be tee-ed to a line that will get a vacuum signal when the throttle is closed (on intake manifold in other words) they have BOVs stock... just use the existing hose

P.S. your going to want to recirculate the air from the valve to before the turbo (between Filter/Turbo)
