The bulb carriers (the plastic piece that goes in the trunk & backs to the lens) are 3 bulb for the 00 & 4 bulb for the 02. I will refer to the 00 as "old" & the 02 as "new". Below are the designations from Bentley manual (for old) & dealer (for new) Plug hole # wire/old wire/new. 1 black/green white/brown. EJoFM.
