Fiesta Zetec 1.25 2009 ECU pin-out

[AA300]

Hi, I have had an Auto-electrician look at an long standing overheating problem and diagnosed to a possible ECU to relay signal issue. We have replaced the fan assembly (multiple faults), and checked the temperature sensors and ECU function - all ok. He said that he has tried to get pin-out information for the ECU from his reference sources and also direct from Ford who have not been at all helpful. I approached the local dealership and requested same info from their service bay, they also refused saying that they are required to carry out their own diagnostics at £80.00 an hour. Can anyone give me the pin out from the ECU to fan relay please? Ford Fiesta Zetec, 1.25, 2009, 3-door.
