I'm assuming this is a GTE and not a GE and also that it's not equipped with EGR? You'd need to follow the vacuum diagram from your region or a Japanese MKIII to put everything 100% straight. I'm not sure if they're available online; The only online versions I know of are for the North American model. You shouldn't have any of the EGR plumbing and two ports on top of the throttle body (the rear most two) will not be present from what I recall.
