Changing the subject slightly, but I hope there are more diagrams and wires than I can see in those pictures?

What is the door sensing? I cannot see any wires that would connect to the door circuits, nothing for immobilisation (although your car should have something anyway in the form of PATS). From what I see there, it will only go off if someone tries to hotwire the ignition.

And don't tell me it has ultrasonics to protect the inside, because they can be bypassed in seconds.
