I just checked the wiring harness in my BA213 with DSSI drives.  The
first 4 cables are the same as those in the 4-pin connector.  The 5th 
cable on each is the little blue cable you mentioned, which join 
together in a little plug resembling those used on some CMOS batteries,
which attaches to the DSSI operator control panel.  I don't know 
exactly what the function of that plug is.
