Positions 1-3 (manufacturer) and 9-17 (year & serial number) are pre-defined and general VIN decoders should supply that info, but positions 4-8 are determined by the manufacturer. KZ might or might not include flor plan info. As near as I can see from the limited info available, floor plan is not included.
This document purports to describe KZ Vin content for 2017 but it appears it might be generic for all KZ years and models.
