Car Alarms: i have a 93 saturn sl1 w/ an after market hellfire alarm, saturn sl1, hellfire

Question
i was @ work today when i went to start my car and it wouldnt start when i bought this car i was told the alarm was unhooked  and the key fob only functioned for the door locks,So after about 2 hours of scratching my head i flipped the valet switch and the car started i would really like to know where to get a manual for this alarm so i can figure out whats going on with it. can you help me  

Answer
It appears that harrison is no longer in business as their website harrison-hellfire.com does not load.  I would suggest posting this question to www.the12volt.com/installbay and see if anyone there might have a manual left over that they could post for you.
