i got a few map sensors, i dont think they are from a GZE but they plug into my smallport loom. i cant see what the difference would be.
i can do you 1 for $50 + postage with a mount bracket. and if it dosent work just send it back and ill replace it with another one as i have a few of them laying around.
you could pick it you if you wanted to im located about 45min south of Newcastle.
