I ordered the leather steering wheel for my Compass Sport, which should arrive in the next week or so. The parts guy said that all of the leather wheels have the audio control built in. He also said something like "if your car has the wiring, we can hook it up, otherwise they won't work".
So, my question is... Does anyone know how the steering wheel audio connects to the car? If my car doesn't have the harness, wouldn't that be something I could add?

It connects through the SCM (steering wheel control module) and communicates for the LIN (local interconnect network). My guess is that there are different SCM units- one for with steering wheel controls and one without- you will need to check with your parts guy about this.
My car has factory cruise, but I'm not sure if that gets me any closer to connecting the steering wheel radio controls. It looks like Jeepster55 left it non-functional. I'll pull the steering column cover off tonight and look around, comparing with the diagram you posted. Not sure if my nickpickedness will let me sleep at night with non-functional buttons in my car!
So, based on the diagrams from the cruise control thread, my C2 plug behind the steering wheel has a Grey/White wire connected, which should be the radio control line. However, the C5 plug inside the steering wheel is missing the grey wire on pin 1.
Sooooo... How do I track down the part number for the inner steering wheel wire harness that has radio controls?
You may need to get sale code RDZP (steering wheel mounted audio ctrls) added to your vehicle build on dealer connect and then vehicle configuration down loaded and then load to you jeep. Don’t think there is an option in the radio to add the controls I will try to have a look tomorrow. I would expect something has to be done and it’s not just plug and play because I would expect error codes on units without the control for open circuits.
I've been digging through the parts database at MoparPartsAmerica.com, they list the steering wheel at $178 for gray and $241 for beige. My local dodge dealer charged me $241.
Browsing through the online database on that site seems to pull up all sorts of inconsistant pricing, and the part description is vague sometimes, which is why I just went through my local dealer, so I'd be sure to get the right part. The switches for the steering wheel look to be about $11 each; not sure if they are part of the steering wheel assembly or if they have to be purchased seperately... My guess is I'll be out more than just the price of the wheel to get audio controls functional.

Reason: lol, I guess f o r k i n g is a bad word?

maybe not, all the audio controls are is a two wire circuit with a resister network that gives different values depending on whats pressed, when no controls are pressed its an open circuit. so no controls = controls with no buttons pressed.
edit: check step 6 below, it says open circuit with no buttons pressed. so the CCN shouldnt give an error even if it expects audio controls and theyre not there because in both cases they are normally an open circuit. IE if theyre not present its on open circuit because theyre not there and if they are there and nothings pressed, its again an open circuit.. it leads me to believe that the CCN will always monitor for the controls regardless of whether it came from the factory with them or not. just guessing though.
3. Use an ohmmeter to check the switch resistance as shown in the Remote Radio Switch Test table
REMOTE RADIO SWITCH TEST Switch
Pre-Set Station Advance
NOTE: The right remote radio switch back is white in color. The left switch back is black in color. The right/left remote radio switch orientation is with the steering wheel installed, and driver in driver's seat.
4. If the switch resistance checks OK, go to STEP 5. If not OK, replace the faulty switch.
5. Check for continuity between the ground circuit cavity of the switch wire harness connector and a good ground. There should be continuity. If OK, go to STEP 6. If not OK, repair the open circuit as required. 6. Unplug the connector from the Cab Compartment Node (CCN). Check for continuity between the radio control circuit cavity of the remote radio switch wire harness connector and a good ground. There should be no continuity. If OK, go to STEP 7. If not OK, repair the short circuit as required.
7. Check for continuity between the radio control circuit cavities of the remote radio switch wire harness connector and the CCN wire harness connector. There should be continuity. If OK, refer to the proper Diagnostic Procedures manual to test the CCN and the CAN data bus. If not OK, repair the open circuit as required.
