This is the corrected ecu plug diagram. I drew this on AutoCAD so i could print each plug out full size a3 for my garage wall. This is a high (ish) res jpeg of the cad drawing.

I personally am not too up on the ac but someone will be able to help you with that no doubt.

As for the engine and box, most things are needed, the egr can be deleted if you have it (but only if the law allows it) check the egr delete threads on this forum.

check this thread in particular-

are you repairing an existing loom/cut loom or are you intending to build one from scratch?

As for help on understanding wiring diagrams i recommend printing out this:-
