Hi Farside. I'm not aware of anyone adding the stock cruise. The harnesses on the F6b and the Full Wing are different. That said, Many folks have added the MC Cruise, and some have added the Rostra Cruise.
Using guidance from here and the F6C forum as a resource, I have added the Rostra, and am quite happy with it. I chose to install the Full Wing right throttle grip (which is not necessary, but makes the whole install look 100% stock). I later helped another forum member here install the same setup on his F6b, and I later added a Rostra to my BMW R1200GSA.
EDIT: I was going back to see if I could find more info for you (part numbers, etc) and found that we had a similar conversation last year. Apologies for the spam and rehashing the same conversation.
