you need to make sure that the colours are as:
blue - cool start injector.
brown - thermo time switch.
black - aux. air valve.
green - knock sensor.
yellow - sensor under inlet (cant remember name but its also yellow

)
if thats right mate then mine is fooked !! heres a pic of mine. the cold start is yellow on mine and where the yellow circle is, its a round temp sender like the one on the thermostat housing but im guessing it should be a 2 pin connector cos ive got a blue connector (which is sposed to be coolant temp sensor) with nothing to connect to!!
