If you have the floor shifter, this may help. Helped me when I got to the airbag module in my 05 Lariat Supercab. Make sure you disconnect the battery and pull the airbag fuse before you do this so the thing doesn't go off accidentally.
Aside from what's in that article, there are also two screws in the back of the console that you need to get. You need to move the seats forward. They're all visible so you can easily see what screws need to come out to get the console off. I didn't need to take the shifter off though, I just lifted the console from the rear end when it was loose and got the airbag module. It's covered by a piece of pre-cut carpet and held on by three 10mm bolts, I think.
Anyway, are you resetting the module because your airbags deployed or are you trying to fix an airbag light problem? I thought it was the module but it wasn't (luckily I could return it). Turned out to be the driver side seat belt pretensioner assembly that was bad. Replaced it, put my old airbag module back on, and my airbags are working again. Well, some will claim they aren't but that thread was closed. Check the number of blinks of the light when you turn the key on, and that will give you an idea of what it is. My code was 5-1
