Don't suppose someone happens to know where the ECU diagnostic (OBD, 3 pin) port is on an S3. Had a look in and around the engine bay but couldn't find it to plug a fault code reader in. Wondering if it's hidden behind the glovebox etc. ?

Port duly found where described smile but interestingly doesn't have the standard Ford traingular port on the end. So the Draper fault code reader adapter doesn't fit. Connector on the loom is a straight inline plug, with Brown, Brown/Green and Blue Green wires which according to the wiring diagrams are the ECU connecotrs. So wondering if anyone out there has found the same, and identified which wires would go where on the Standard Triangular port ? Wish I still had my Sierra to check in this instance !!

Thanks guys, wire/ pin arrangement spot on smile. Hooked up the fault code reader and happily set everything into service mode, and then did the ECU fault read out for which there were none ! Only thing the FCR doesn't seem to do is read the ECU when only the ignition is on... but otherwise all good.
