Another picture....?
In some cases when you try to shut the vehicle off, power from the alternator can feed up to the coil and keep the engine running. To cure this you can install a diode in the ignition wire that activates the #1 terminal. This will stop the power from feeding back up the ignition line. These are buck or two at Radio Shack, just be sure to put the stripe end toward the alternator to stop any flow.
