This is for reference for those who look to do this in the future. Neither of the two methods mentioned above worked on my vehicle, as the cover is attached in a different way. I got the job done, though, using the same method as [MENTION=336]03_4x4Runner[/MENTION]. I tucked the wires under the edge of the A-pillar cover, and ran them through the same hole in the top of the dash that the other harness is run through. Below is my A-pillar cover, and the black plastic "keeper" on the back of it that prevents it from coming off. There isn't enough room to get long-nose pliers or another tool on the keeper to remove it. It also appears that the air bag is attached to the back of the A-pillar cover.
