[QUOTE=rgwm;4933796]Jeepers, how can a thread be so difficult to understand....?
The OP has obviously got the full set-up that he wants to change. He correctly knows that you need to replace the ECU, the immobiliser box (or code reader) and either the key and barrel or just the immobiliser "chip" in the key - all from the same donor car.
All he wanted to know was where the immobiliser box was - answer, for anyone else who wants to know, is that its bolted with two 10mm bolts on top of the framework that the main fusebox under the dash is bolted to.....it is a PITA to get at but once you've located it, some long 3/8 extension drives should let you get at it....I have found the odd car where its just been loose under the dash - probably because someone got one out but couldn't be a***d to replace it
Sorry to the OP for not seeing this thread earlier - been away for a few days. But whilst I know that everyone who replies is well-intentioned, can I humbly suggest that if you don't KNOW the answer to a problem, it may be better not to muddy the waters with vague speculation - or downright inaccuracies?
EDIT - for GTVTommo - only time you can replace an ECU only is if you use a brand-new "virgin" ECU. A pre-used one will not work without a matched set as above.[/Q
For what its worth my opinion rgwm is you never learn unless you ask and sometimes you think you know the answer and pass that knowledge on rightly or not so yes thank you for the info which I did think thats the way it works although I didn't realise the bit about fitting a new ecu so I've learned something there........with respect to the OP and indeed yourself the original question was "where's the transponder located" it was then edited to read as it does now following some obvious replies so I suggest he/she got the right answer in the end more especially now as you have clarified 'how things work' so well. Having said that point taken about the 'muddy waters' bit.
