The truly observant may have spotted that I used an ESP switch for the pictures; I was going to fit it and make it work properly as per the Focus ST, but the insurance company didn't like the idea of a safety related item (i.e. the braking system) being modified so that rather put the mockers on that.
P.S. If anyone knows what colour silver (Moondust Silver ?) the switches are painted with then I might recycle the ESP switch (by changing the emblem) for switching my front parking sensors on and off.
