Catalog file labels
89663-60B80.bin names a binary file for this identifier. The related label 89663-60B80-A adds an A suffix, but does not state whether it represents a stock or modified variant, or name a feature it changes.
These labels are useful for identifying the catalog entry, but they do not establish fitment for a particular Toyota or Lexus model.
