We are supposed to be able to install the switch ourselves by just buying the switch at the dealer. Since our rides are drive by wire, all we have to do is splice in 2 wires. But some say the 2007 and up are missing those 2 wires if it didn't come with CC. I haven't checked mine yet. Those 2 wires enter a harness under the dash. Now, I haven't had time to try this but do look into it as many people have pulled it off!
