7 or 8 wire Regulator/Retifier

Long story short my battery went flat on me. Wasn't holding a charge. Got a fresh one and doing the different tests a.k.a "The Drill" showed the battery wasn't charging.

Swapped the "new" Ricks R/R that the previous owner had on it with the old one he was kind enough to supply with the bike and the bike is charging fine now.

However I noticed the "Ricks" R/R has 1 less wire and connector than the working R/R and the VFRness that it plugs into.

Can anyone shed any light on this? Why there is a 7 and an 8 wire R/R?
Did the previous owner slap on the wrong R/R?

Here is the supposed "Ricks" reg which I removed and noticed the 1 missing connection:




The old one I put back on and is working fine now. It has 5 wires in the connector where the other R/R only has 4:

 

I'm doing some more research and I think maybe the 7 wire regulator (3 yellow stator wires and 4 others) are for the 1998-1999 VFR800, and the 8 wire regulator (3 yellow stator wires and 5 others) are for the 2000-2001 VFR800?

:cower:

 

The 98-01 service manual only has a single diagram and the RR has 4 wire outputs. The 6th gen has 5 outputs.

 

I noticed that aswell, however Honda lists different part numbers for the 98-99 and the 00-01.

I think I read somewhere that in 2000 they added some kind of accessory wire monitor and that is where the 5th wire comes into play.
