Wiring on the dafs absolute shite. As is dealer support. For the majority of dealer workshops have technicians and/or fitters if computer (davey) tells them what’s wrong they can fit new parts after that they ain’t got a scooby
What the lad from ford and slater said is correct both sensors go to that modulator valve .But for some odd reason the right sensor wiring goes from the sensor to the bulkhead on the F plug then loopes straight back out the D plug to the modulator ..Maybe its the engineers way of having fun when he designed it as there is no sense in it
