shaung60 0 Posted September 16, 2009 If a Mod coms along and sticks this in the Engine Bay section then you might get some more replies but I know there is a pipe from the ECU to the back of the throttle body area. There is a second pipe but I can't remember where that goes. Quote Share this post Link to post Share on other sites
