hi all, today i got a manual boost controller from ebay, its the one with the heading "wrx sti p1 manual boost controller" its the blue 1 in the box pictured with the yellow hose. theres 2 pipes on it,bottom pipe has arrow out and theres a t piece with arrow. i have fair idea how to fit but when i checked google theres a few conflicting ways on how to fit. im not gonna leave this on just wanna fit it to check boost issues ive been having and narrow down my prob, any pic on how to fit this would be great
