so i know your thinking i have a lot of questions lol it keeps your guys minds fresh lol buuut i was looking at a way to hook up my cooling fans back to stock and noticed a hard line that was missing a hose and followed it back and it leads to next to my oil filter. theres two of them and the top leads to a black box on top of engine which im guessing is some emissions crap?? anyway any clue on where the bottom one goes or if its even important ?thanks guys
