Plug -n-Play is what I was told by the dealership. Not exactly rocket science when I read the "Destructions" but also not PNP. I guess I will have to get the Service manual for this bike also, As I do not currently have it. I think my least favorite phrase in the Instruction sheets from HD is "See the service manual to....." Maybe they should just rename the enclosed sheets from "Instructions" to something less optimistic. But I gotta give 'em credit... At least the do say "This instruction sheet refers to service manual information.... Available from an HD Dealer" So, as opposed to the pressboard furniture, at least I know there is better information available than what came in the Box! :s
