A bit harsh Phil, Mark does have a point!
Have you even had a look at the car??
Autodata does have some wiring diagrams but mondeo 2.0 diesel 2008 tells us nothing.

If you can't be bothered to check yourself, at least give us the right model info, engine code, hp etc, there are several different variants and someone might tell you.

I'm guessing it doesn't have electric pump or cut off switch.
