Question
where is the computer access point for diagnostics please

Answer
Neil,

If yours is 1996 or newer the connection is just under the dash on the driver's side.  If yours is earlier the connection is not really a connection and it is a matter of looking under the seat or the kick panel for the computer.  There are lights that blink a morse code when you use a common screwdriver to turn the screw.  Email me back with the year and we'll go from there.
