I have a secrity backup battery and was wondering if it would work on the factory alarm? Thanx.

You could hook it up but it wouldn't work that great. Reason is that the cars door pins wont have power to send a trigger to the alarm if the power is cut which will just leave the alarm on doing nothing. If security is that important you best bet is a nice aftermarket alarm.
