On a 93, you use the diagnostic connector under the bonnet next to the
windscreen washer filler, attached to the front of the ECU box.
There is a fly lead which you plug into a different hole depending on which
system you wish to read codes from. You then invoke them by pressing the
button and watching the red LED.
I can give you the button pressing sequence if you say which systems you
wish to read specifically.

Replace tt with t (twice!) and remove parentheses to email me directly.
(But I check the newsgroup more often than this email address.)
