Air Bag Simulator Disconnect Kit

My car (1995 Deville) has no airbags (they've been deployed.) Thus, there is a Service Air Bag Systems light flashing on the dashboard computer. Someone told me a cheap way to solve this problem (get the light to stop blinking) was to trick the car into thinking it still had airbags. He said I should get an air bag simulator. I did a search on google and came across this site:

Has anyone else had to do this or had any experience doing something this? How easy was it, any problems, etc. Hope someone can help, the blinking light on my dash is driving me crazy! Thanks!
