Has anyone had this problem getting the right wiring diagram?

I've had a intermittent long cranking problem with my wife's 2006 Fiesta 1.4 tdci which I thought I'd cured with a set of fuel lines as there was air present and new set of glow plugs as only one was working. Both checked at least 5 times now, no air and 46amps!
The live scan data from my Autel MaxiDiag didn't point to any other faults like a temperature sensor or fuel pressure at start up and it runs fine once started so I'm thinking cam or crank sensor possibly!

So I thought I'd check both at the ecu/pcm with an oscilloscope but I cant identify the wires so I've been trying to get a wiring diagram but no ones been able to tell me if its a Stage IV or Euro 4 version (I'm not sure how many versions there are but that's what I've been told) or give me the correct diagram with correct pinouts for the ecu/pcm.
