2005 Vectra CDTI 120 crank sensor removal

[rhyds]

Anyone know where the crank sensor is on a 2005 Vectra 1.9 CDTI 120? My cousin can't seem to find where it is on his. All the advice I can see points to it being on the back of the engine *somewhere*

Next to starter motor I think. White plug

As Critch said, sensor on the back near starter with one bolt
