Duratec engine, it was Raceline's development car originally! Aha! I suggest identifying all of the wires and how they are connected at the alternator... layout, colours and whether each is thick or thin. I have a pic of the tacho, but need to look up how to upload it... Start with the Forum User Guide, and let us know if you get stuck. Jonathan PS: I suspect that the mystery light is the unused ECU warning light... or dampness indicator.
