Lane B Dead

I disconnected the battery some weeks ago to relocate the battery box and after reconnectnig today, Lane B is totally dead.  No auxilary fuel pump, EMU is receiving no data on Lane B, no warning lights for either Lane A or Lane B, etc.  HIC A and B were never disconnected nor were any other harnesses, connections to fuse box, etc.  I've not opened the fuse box yet but will start there.  If anyone has an idea on where to begin tracing this down, I'd appreciate some advice.

Thanks.
