Welcome to Club Lexus.

Is this the original country the car was meant for or had it been imported? Is your a left or right hand drive? A '96 ECU should also be compatible. Is there a salvage yard that has parts for these cars if this is a possibility then you can inquire if they have an ECU.

Asa reference we have this thread of ECU part #'s for the US and some other countries listed:

Is there a dash warning light/check engine light that is illuminated? If you can get the error codes read we'll be able to advise more.
