Where does the power come from for the pump its a white/blue wire i have found a range rover classic drawing but the ECU shown is a 8 pin plug and the one on mine is a 15 pin ( i have been told this may have been used on a disco). i would like a wiring diagram to look at does any one know of a site i could download 1 from
