Help with alarm please

[96 Vortec]

I have an older alarm that is malfunctioning.  It is an Ungo MS7000.  Anyways, the pin switch on the hood is missing and there is a loose wire now.  I have it taped up unitl I get the correct pin switch.  

 

Now the problem, after I remote start my truck, about a minute later, my alarm will start going off.  

 

I know I've got a pretty slim chance that anyone knows about a 5 year old alarm, but would anyone have any suggestions about some sites that would be of some help?

 

TIA

Jeff

try checking the vibration sensor, it might be too high and the vibration of the vehicle is turning it on.  Just an absolute guess though.
