$27.01Now those parts with some cutting time on the factory trim would do it just like I did. So if you did it this way your total cost to add these suckers using new parts would be:
$52.89Now if you didnt want to have to cut anything you need to order the rear plastic trim, the plastic costs
$18.08 shop price.(25% discount over RRP)
05086215AA - COVER, Steering Wheel Back
So for about
$71 total you could add this via new parts from the dealer and it would be a completely "bolt-on" mod. If you found a WJ with the buttons and harness and spent a little time installing the radio wires into your harness, and cut out your old plastic, you could do this for only the cost of those used parts from a junkyard.
You can take these part numbers down to your local dealer to order them, if you do that you may wish to print the following 2 pages of the PDF that shows all your needed parts(the parts needed are listed as number 3, 9, and 11 in the pdf):

The install:Very easy to do, took about 30 minutes overall. I got the parts at the junkyard last weekend, unfortunately I wasn't able to pull the rear steering wheel plastic which has the cutouts for the buttons, however its pretty easy to dremel them out and install the buttons.
Disconnect the negative battery terminal. Go inside and enjoy a beer for about 20 minutes.
Start by removing the airbag, there are 2 8mm bolts that hold it in place, once the bolts are out the airbag will come forward, disconnect each airbag connector from the back along with the horn connection. Set the airbag aside in a safe place facing upward.
loosen the 13mm bolt and unscrew several turns.
Unscrew the cruise control buttons from either side, unplug them and set them aside. Disconnect the steering wheel wiring harness from the clockspring.
Use a gear puller(traditional steering wheel pullers will not work since the KJ steering wheel does not have threaded hold for the puller to screw into) to remove the steering wheel. Feed the airbag wires through the rear plastic cover and set the steering wheel aside.
Make sure not to turn the clockspring, dont worry about aligning the wheel, there is only one configuration that it can be installed with.
Remove the rear plastic from the wheel, remove the wiring harness.
Use the cutting instrument of your choice, mine was a dremel with a drill bit and a razor blade to cleanup the cut, and cut along the mold lines seen on the rear plastic, tweak as needed to get the buttons to mount, alternatively if you are able to get the rear plastic you will not need to make the cuts for the buttons.
After cutting and installing the buttons install the new steering wheel wiring harness, it will be obvious, it will install in the same place as the old one you just removed.
Install rear plastic on the back of the steering wheel, install cruise control buttons, replace the screws holding them in place, and make sure the cruise and radio buttons are plugged in.
Feed the airbag and horn wires through the rear of the wheel, there is only one orientation that the wheel can be installed with, take your 13mm bolt and tighten it down nicely.
Plug in the horn and airbag wires, place airbag on wheel and reinstall 8mm hold down bolts.
Reconnect battery.
Enjoy beer while sitting in Jeep changing stations from the steering wheel.

Got them all in and working, pretty cool little thing to do for as cheap and easy as it was. Total project time was about 30 mins.
