You are in for a real treat! While I have not pulled the dash on my JKU I did have to replace the air distribution box on my 2011 KK. I bet they are similar so here is what I did or remember:
I started with an online subscription to Chilton. It's good for some step by step, but more importantly torque specifications. Disconnect your battery! This type of work could trigger the airbags! I recommend that you mark original positions of bolts and items to be removed with a paint marker for reference. Next I pulled the center console, kick panels, and A pillar covers. Then all the dash accessories, controls, radio, gages and cover panels. With the front drivers seat all the way back, drop the steering column to the floor. Unbolt the brake booster and drop the steering column bracket. You might have to drop the pedals too. Then the dash bolts, six total, four from the top and one behind each kick panel. Disconnect all necessary wires and carefully pull the dash forward to the front seats
When you are done with your repair just reverse the process. If I remember right there are specific torques when reassembling the steering components. Working slowly and patiently is a must! I hope that helps! Good luck!
