Could any of you guys please tell me where my ECU is located on MY 03 STI ( 8 ) as I have tried looking everywhere for it,as I need to locate the speed pulse wire to connect it to my Sat Nav ?

Thanks for any replies

It's in the passenger footwell. Pull back the carpet and you'll find an aluminium cover, it's under this.
