    Hello,

    the engine is finally in, now I need to sort out all the wiring.

    Can someone confirm if the connector going to the air flow sensor (see attached picture) is brown?

    Blue = cold start injector
    Black= Aux air valve
    Grey = WUR

    Large Black = TPS
    Small square brown = ECU Engine temp

    Black and white pair = CPS

    Small connector: oil warning switch (at the oil filter base)

    Larger connector = oil pressure sensor

    Engine temp gauge sensor = HAVE NOT FOUND IT

    Down in the oil sump, right side: Oil temp sensor

    Not sure about the plug colour, but the cables should be
    - white and red on the TT switch
    - black and orange on the cold start injector
    - purple black on the airflow sensor

    Updates:

    Engine temp sensor for the gauge: small spade connector, in the right bank cylinder head.

    Air flow sensor= Brown connector (only one, driver side on LHD cars).

    That’s correct. Also, when it’s unplugged and the ignition is turned on, the fuel pumps run continuously.
