Related catalog identifier
The related catalog entry is 89663-33N60-C. Its -C suffix distinguishes the listed identifier, but does not by itself establish whether it is a stock calibration or a modified variant, or identify a particular feature.
The complete identifier matters when comparing records. A similar 89663 prefix identifies the broader calibration family, not necessarily the same vehicle application or software revision.
