I did not drill my dash either. There are a couple screws that hold the dash on above the brake pedal and gas pedal. I chose to use the one over the brake pedal. It took me about 5 minutes to install mine, it already had the ford adapter attached. One screw removed from the dash, re-insert screw with the adapter bracket, plug in wire harness then make sure you get the rest of the cord out of the way and you are good to go. I do agree that an integrated controller would be awsome.
