The 2011 JK has the new interior so the cruise control switch is in the steering wheel. The 2007-2010 JK has the cruise control switch on the column. The 2012+ JK has a different ECU due to changing to the 3.6 & NAG (somehow that is relevant to cruise control).
The 2011 is pretty much a stand alone year. Several of the electronic parts will only work in a 2011. My understanding is the cruise control switch in the steering wheel has to be “rewired” inside the switch itself for the cruise control to work. I believe AEV includes this in their kit for the 2011 (which is why the 2011 kit is more expensive). Todd at Jeep Speed Shop will sell you the switch.
I have a 2011 JK using a JSS 5.7 kit. I don’t have cruise control right now either, but that’s only because I haven’t bought the new switch yet. I have too much fun with the gas pedal anyway.
