The rest of the hardware should also connect straight to the current connectors, and I agree that the programming is the biggest obstacle. However, even that should not be difficult if a formal request is made thru the right dealer as you did for your retrofit.
I'm getting the new controller first for testing as long as the connector is the same, but so far no part department that I have called have both controllers in stock to tell me right there that the connectors are the same...
Great stuff!! It definitely makes sense.
