excalibur al900gtx manual

hi folks, Does anyone know where i can get a manual for this alrm in either paper or electronic form so i can try to get it working? i just bought a 1992 mustang and while cleaning and getting familiar with her i found an alarm control box, excalibur al900gtx. the wires are all connected to their proper parts i suppose however there is no blinking red alarm light anywhere in the car. the previous owner was an older man and it was his son who was selling it and he has no info on the car or its electronics and no keyfob transmitter. i wrote to Omega products after some research told me they manufacture excalibur but they say the alarm is too old and they offer no support for it. thanks, johnny
