    Need your help guys - recently removed head and replaced new head gasket etc - put it all back together however have one plug and dont know where it goes - its a 2 pin plug with 2 wires, one brown/blue stripe and other brown/white stripe and situated somewhere near to battery.
    Also engine won't start - any suggestions? - is getting fuel and sparking.

    Because of the brown (with stripe), I am guessing they are a switched ground wire, perhaps related to a sensor, e.g. intake air temp sensor, or maybe idle stabilization valve. (I just checked my AAN wiring diagram and the intake air temp sensor on it is connected to the ECU via a Brown with blue stripe wire so that is a good clue for you).

    If noboby gives you the right anwer, you will need to search through the S2 current flow diagrams under the Technical, Electrical section of Paul Nugent's website:

        What about the intake air temp sensor? That's the one with the correct colour wire. Not that the intake air temp and idle stabilization plugs are identical and have been known to be swapped by mistake.
