The new electronic circuits are smaller, but they require more power than their predecessors, there are more of them, and the sensors have placement requirements which conflict with the aircraft's configuration. All of this adds up to having to re-wire the aircraft, do a new layout, and move around a large number of parts.

That makes no sense at all. It is a nonsensical statement.

Unless what you're really trying to say is that the stuff designed to fit a different specific aircraft can't be directly bolted on to an A-10, then I simply don't find those remarks credible. And if you are trying to say that, then you aren't being reasonable.
