Car Alarms: How to disconnect Alarm, black widow car alarm, dash panel

Question
I need to know how to disconnect the motion sensor on the Black Widow car alarm.  The alarm was installed by the previous owner and I didn't receive a remote.  The alarm  was disconnected but recently the motion sensor was triggered and the car is immobilized.  Need help quick.  I cannot afford to tow the vehicle to the nearest shop.  I live out in the country.  

Answer
If you take down the dash panel under the steering column you will see where the wires were tapped in to the ignition harness.  Follow these wires back to the brain of the alarm, and remove all fuses (if any) in the harness that supplies the brain.  If there are any fuses in the brain itself, remove them as well.  This should render the security system useless.
