I am wondering if I can read codes from the ECU on my 89 300E as I was on my 300ZX. This was very helpful when I had assorted problems over the years. Also...I hate to sound dense, but where is the ECU for this auto?

Thanks!

BTW....This forum is so much more civilized than others I have attended.
