This is nmz787 here, glad people found this work useful! I have had absolutely no issues since modifying my truck, there's no side effects at far as wifi or radio lock out. The wiring is only going to and from the knobs just below the screen, the touch screen input, and the actual screen backlight itself. When I was debugging this, I ended up simply pulling each individual data line one at a time and testing the dimmer until I found the magic wire. One wire disabled the knobs, the next disable the touch screen, and then I stopped after the third one which was for the dimmer override.
