wpoll will become famous soon enough
There are pin assignment differences, along with bulb differences and differences in the circuit tracks in the tail assembly.

The pre-LCI uses a dual filament 5W/21W tail/brake bulb while the LCI uses a single filament 21W bulb that is PWM modulated from dim (tail) to bright (brake).

This change may have occured prior to the LCI change date (09 2003?) as BMW modified the assembly line for LCI builds. The change in tail lights would also infer a change on the LCM etc...
