I guess part of the above might be for the amber indicator? I'm in Australia so that is standard so might be even simpler to swap in some LCI tail lights as they look fantastic!
I'm no expert here but I'd venture to guess that since pin reassignment is required, which means the wires reassigned have a different function or purpose than before, that coding is needed to tell the module what the new assignment and functions are for each wire.

The fifth wire has to be for the separate amber blinker since it is not required on US lights and just Euro and it's the difference in the lights.
