Motorcycle Repair: The cruise control does not work on my 03 Ultra Classic, seperate unit, harley ultra classic

Question
I have a 2003 Harley Ultra Classic that the cruise control does not work. It worked prior to taking it to a local harley dealer where they installed a race tuner kit, a big bore kit with HTCC heads, pistons, and intake.They also installed the recalled main breaker. Since the upgrade the cruise control does not work. The dealership has changed the wiring harness, the switches on the grip and on the fairing and are telling me there is nothing they can do. My question is, is the cruise control electrically controlled through the ignition module and can the cruise control be not recognised by the current ignition module? If the cruise module seperate from the down load module is there a sender in the new manifold that is defective and should be checked? Please help  

Answer
I dont know alot about the cruise control on the harleys, since I really dont work on them, but I do know that they are controled by a seperate unit. If it were me, I would take the bike back and insist that they fix it since it worked when you took it in there. If you get no satifation from them call harley and take to the customer service department.
Sorry I couldnt be more help
