01 mondeo wiring info needed, specifically speed pulse info
 

Hi All
Have just recently bought a 2001 Mondeo 2.0 Zetec, a nice car in all respects
I wish to fit my sat nav system into it ( clarion single din )+ clarion single din MP3 and need to know where to get a speed pulse signal from, it's normally out of the ECU or the Clocks, but I need a pin no and wire colour or some kind of schematic or wiring diagram
Can anyone help please ?
