A very nice schematic and with a bit of colour added too... Thanks for posting Richard, however without the parts description relative to the numbering it seems a bit like those electrical schematics where the wiring connects into various blank boxes (ECU`s Nodes etc.etc.etc.) with no description as to the switching actions within...?
As best I can make out neither schematic seems to have the heat exchanger ( oil heater/cooler) that is part of Dave`s schematic...?
