One of our fine tech's usually shows up about this time of day that can answer the FICM sync/no sync questions better than I can. I'm not aware of any specific date with the 04's that the harness was changed but I know they have issues. Harnesses are around 3-400 bills and yes, they are a pain to install but very doable. Did you by chance double check the FICM plug-ins? Sometimes they are a pain to install and come loose or don't get "clicked" into place and cause immense problems.
