Hi Roy, Found a copy of the Owner's Manual for the Ft-991. The short answer to your question is, yes, there appears to be BCD Band Data Lines on the Ft-991's 8-pin Mini DIN connector labeled for Linear. Actually, the connector and pin out definitions appear to be exactly like the FT857/897 series of radios, too. I believe you'll need to make a MENU change in order for it to work, too.
See Page 12 in the Owner's Manual for wiring for Basic mode operation with the KPA500. Yaesu seems to hint that there's a cable available for that connection method - most likely through their parts department. See page 21 for a definition of the Linear port. I suspect there's a pin-out diagram in the back of the manual that will match the Yaesu pin out table in the KPA500 Owner's Manual for the Band Data signals.
