Cheers for that, have seen that diagram before and thats why i thought it was the connector for the diagnostic connector etc, but am not 100% sure, does anyone know how you read the pins on the ecu, its one of the pins from the end of the the multiplug but looks like it could be either, octane and idle adust or the diagnostic connecter etc, also why are the pins on the loom multi-plug not in numbered order etc, Cheers SEB
