You need the whole assembly, the turn signal part, clock spring, and heated wheel.
All together you need a flat head screwdriver about 4-6 inches long, t20 torx, and 13mm socket (deep or with 3 inch extension. I used an impact but a normal wrench will work.
It only takes about 10 minutes to pull it all apart, the hardest part is the air bag. The steering wheel takes a 13mm bolt, the rest are all T20 torx.
First you remove the shroud around the steering wheel. It has 3 torx screws, 2 are long black 1 is a short silver under. All 3 are under the steering wheel from the bottom. Remove the air bag, youtube will kinda get you there, its a pain in the rear. Then you will see a giant 13mm bolt staring back at you once you un-clip the airbag. There are about a million harnesses to disconnect, then pull the wheel off. It took some banging around and fussing with it but I didnt need a tool to get it. Then you have the clock spring and turn signal stalk. Pull this all as once, you do not need to seperate it. The turn signal base does not have the provision for the heated wheel harness, it wont work, dont try.
All that work then reverse to install the wheel.
Here is the sad news, for me it was a waste of time. I took the whole assembly from a longhorn with everything. Tested to make sure it worked in the other truck before i took it out and installed in mine. It did not work. The steering wheel did not heat, the light would not activate, and cooled seats were dormant, again for me nothing at all. Waste of time for me. So I reversed it all again, put back in the longhorn, and darned enough it will activate the heated wheel.
Now on a side note, when I removed the wheel from the longhorn, it will still allow the cooled seats to work.
