Close! AoA disagree hazard light was an optional feature. In the original implementation, the Flight computer in command, either the one on the pilot's side, or the one on the copilot's side (alternated on power up), were fed input from only the AoA sensor they shared a physical link with.

The optional feature was essentially networking the two ststems such that the data would be fed to the FCIC for warning light activation, so that pilot's could start running the right checklists.
