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:

thanks for your suggestion mate but it not the idle stabilisation valve and the plug is identical to injector plug.cant read diagrams(have tried for 6hrs)amgoing insane
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.
