hi im doin an h22a into a 92 accord lx. anyone tell me what this electronic vacuum controller thing located behind the oil filler cap is. http://www.hondaswap.com/gallery/images/s40414648222f2.jpg it hooks up to the vacuum line between the fuel press. regulator and the intake. i havent been able to find what it is on my wiring diagrams. anyone know? or is it just emissions crap. the f22 just has a hose going between the fuel press regulator and intake manifold. when i put this baby in id prefer not to set any codes.
