I tow a Tacoma and had a complete set of instructions that came with the dive shaft disconnect. Follow the instructions and use it for a check sheet the first few times towing and you will be fine. I did have a non chipped key cut that I use while towing. That way you do not have a ring of keys swinging that can turn the ignition switch. Also you can lock the truck and not worry about anyone stealing it as the dummy key won't start the truck.
The Tacoma makes a great toad, I have about 40,000 miles towing mine.
