I was wondering if anyone has this alarm or know if the door trigger wire have to be connected for the alarm to work right? i think in install manual door triigger wires had to be connected with manual transmissions but not with automatic like i have in my 94' pontiac bonneville. when system is armed i've noticed the alarm(horn) going off for no apparent reason. thanks.
You have an automatic unit. If the model has an M at the end of the model number than in the case it would be for a manual transmisson vechile.
You will need to connect the door trigger to have the alarm work correctly.
For your car the door tigger wire is (Dark Blue or White), it is negative polarity, you will find it at the drivers door harness.
Once you find door tigger wire connect that to the GREEN wire on the alarm unit.
Ultra start unit - Green Wire - Door Pin Input (-) - Input to detect open door. Connect to door pin that switches to Negative when the door is opened.
"when system is armed i've noticed the alarm(horn) going off for no apparent reason."
Check your hood pin switch and make sure it is working properly and not touching ground some of the time.

Be careful whose advice you buy, but be patient with those who supply it.
