Partial success today! I installed the steering wheel controls and they worked just like they should. The voice control button works perfectly!
To remove the old controls and install the new is a very easy job which took me less than 30 minutes. First thing you need to do is unplug the negative terminal from the battery. The power needs to be removed for at least 90 seconds before messing with the airbag. Next, remove the 2 plastic trim pieces on the left and right side of the steering wheel. Once removed you will use a T30 Torx bit to unscrew the airbag. There is one screw per side. Once unscrewed the airbag will pull right out. Remove the ground plug from the airbag and then the black and orange connectors. To remove the connectors you need a tiny flat head screw driver to pry up the yellow portion of the tab. Once that is done use the small screwdriver to pry the whole connector loose. Search Tacoma steering wheel removal on Youtube to see a video. After that you just remove the 4 phillips head screws holding the controls with a #2 screwdriver and then unplug the controls. The controls just pull off the steering wheel. Install the new controls by just going in reverse and that is all.
I have an audio buddy of mine making the extra wire I need and it has not arrived yet. I will post an update and some pictures when I get that installed.
