Adding steering wheel buttons and DIC

Here's my project. I bought a 2005 4x4 1500 CC and didn't get the controls! I want them! I've found many informative articles on how to add the DIC info with override codes that need to be performed at the dealership. I've also seen a couple articles on how they bolted on the wheel and it worked. Guess I'll find out. I've contacted my dealership and they sounded like they would do whatever they could to help with the instrument re-flashing.

So, the new wheel with buttons is on it's way. I have a nice set of instructions on how to safely remove the airbag. What I don't know is if I will need any additional items such as a wiring harness to go between the new wheel and where ever it's supposed to plug in. Anyone know???

I'll try and take some pictures of the project which may help others interested in a project like this.

Thanks!
