It's been done in very good detail on another thread by bstroh59. He did a great job with pictures, and was very helpful to me when I did mine.
I would suggest a service manual though so you can understand the electrical, ands I needed to see how the darn thing came apart.
If you are like me and never in my life worked on a goldwing it's likely to take more than 8 hours though. I have about $400 total in mine. The MC Cruise comes with the brackets needed and the electrical is much simpler I understand.
My Rostra works great, I also have heard the MC unit works just as well.
And NO I doubt there will be a kit from Honda to retrofit. Also to answer a previous poster, no you can not simply buy regular Goldwing stuff and have it work on your F6B, the wiring harness is completely different, and even the cruise boss is not on the throttle cable hook up on the throttle body. That bracket has to be made for the Rostra while the -------- unit comes with it. Personally from what I have read I would go -------- for simplicity, But if you have the tools and equipment to handle making the brackets, and don't mind splicing into your electrical system in several places the Rostra works fine for less $'s.
You can spend your whole life chasing the newest gadget, but if you do you will never be happy, cause new gadgets never stop coming out. Would I like cruise control. Yes. Am i "pissed" that Honda is offering it now on the 2015s, 2 months after I bought my 2013 F6BD. Nope. Not even a little bit. Got a great price on my bike, and I think it is, as we Bostonite's like to say, "Wicked pissah!"
I put a lot of thought into my purchase and don't regret a thing. There will always be a new shiny thing that someone else has that you don't. Oh well, life goes on.

Tell you what. I am NO expert. I have been working on bikes, and restoring cars most of my life. Although most of my bikes were Harleys I have had mine apart for paint, and cruise installation and I do 100% all of my own maint just like several of you. A dealer will never touch my machine, I simply don't have the trust in any of them locally. I see there are several people from Tennessee, South Carolina, and Kentucky.
If a few forum members want to get together at my plant in Brevard NC, and someone will buy and bring an -------- kit I / we will install it so everyone interested can see what it takes, and hopefully we can share the know how, and have it spread around so every one that wants cruise can have a resource to lean on or call. I will not assume any liability, but offer this up as I have had several people asking and know the frustration of wanting an option that should have been on these bikes out of the gate. Hell we might be able to do a few at one time?
For some, chasing the newest gadget IS what makes them happy. I kind of get that because in general, I'm a gadget guy. An inconsistency for me is that I like my motorcycles fairly stripped down. The F6B actually has MORE gadgets than I normally would like... but I'm getting used to them.
* For some people, it's complaining that makes them happy. I don't get that. But whatever.
