Catalog identification
The related catalog entry uses the same complete identifier, 89663-42711. It does not name a vehicle, controller model or stock or modified variant. The full identifier is useful for distinguishing this record from other Toyota calibrations, but it does not by itself establish interchangeability or fitment.
