The blue plug, don't know, but not needed to run the engine. Think that splits from the engine loom quite easy



The black lump attached to the metal bit, egr sensor parts I think, needed to be plugged in , but ports blanked off.



Can't find the photo of my loom laid out,


Can sort something out and pop round tommorow if you want, would be 2 ish, if that's any good?
