De cluttering engine bay

[monkeh]

A few things I want to get shot of, just to eliminate vac lines, Making it simple to spot and work in, and make look tidy.
EGR, Boost pressure warning...
Can these be removed without ill effect?
I have a few sensors dotted around the wing area, I understand that the inlet manifold goes to a tee on the injection pump, from there it goes off to the bottom of the engine to the cold start coolant feed, that goes up to what I assume is the boost pressure sensor.
Can anyone give me advice on what needs to stay and what can be disconnected and removed?
I do have a boost gauge in the cab so rises in boost will be spotted.
