Hi, the ECU (engine control unit) is located under the passangers side foot panel (if your sitting on the passanger's side, where the tips of your feet hit). Remove the floormat and there should be an area of the carpet that is partially detachable, being held by velcro. Under the carpet there should be a wooden board which you can take off by removing 4~5 10mm bolts. Once you remove that the ECu will be the brass colored metal box with all the wires pluged into. There are 3 10mm bolts to remove the ECU. Hope that helps. :)

    Forgot, you can also access the transmission computer/control unit and the power steering compter/control unit in that same location. They are next to the ECU, the two smaller grey/silver metal boxes.

Original rear wing 1990 300zx z32 need to know were to get one


You may have to look at Kaminari - they're an aftermarket company that makes a wing similar to the OEM TT wing. You may have luck with Courtesy Nissan in Texas though - they have a ton of stuff there (www.courtesyparts.com). Or if you don't mind one that is used, call up Z1 Motorsports in GA (www.z1motorsports.com) - they're a 300ZX salvage yard and tuning company. They'll have one for sure.
