Some info on accessories codes below from a site with 68 info for information purposes. Also picture of 68 data plate: from GTOALLEY, and not mine.
Think they (PMD) may have changed this practice at some point (or this info is wrong) and they only used group numbers? Not much room on these so this may be the spot.


If there are accessory codes on the data plate, these codes primarily identified equipment or options installed. Some codes only identify option and not specific equipment. The accessory codes are made up of a number (except 1) and followed by one or more letters. The number in front of the code identifies which group the accessory belongs to.
5 groups make up the codes:
(1st Group) T = power bucket seat, etc.
(2nd Group) S = rear manual antenna, etc.
(3rd Group) N = roof reading lamps, etc.
(4th Group) F = remote mirror, etc.
(5th Group) O = decor group (Le Mans only), etc.
