ok i put a custom air intake on today and was just wondering what the 2 iec plugs were for that connected to a metal thing on the orignal airbox! what ever it was the car wouldnt start unless i connected them back up to it again! if someone could shed somelight if ihave done it right. i removed the orignal airbox and unplugged the MAP sensor and removed the orgianal box. i put the k and N onto the map sensor and then connected the 2 plugs to the random metal thing. is there anything else i need to do as i dont want any problems?
