alarm won't let my car start???

[memario213]

so i tried starting up the car yesterday to the filter change and the battery was dead, no problem i had it recharged i get it in and i go to start the car and then an alarm goes off for a 10-15 seconds turns off for a couple seconds and starts again. and its not leting the car start. i didnt know the car had an alarm. so today i tried looking for some wires to disconect the alram, but i didnt find much. i think i found the horn for the alram it is mounted in the left (passenger) side behind the light bulb location the wires look like there for power and ground only and they run to the side of the fenderwell, the wires go under a box i thought they might go into the car, so i took off the passenger carpeting and took off the heat sheild and i found alot factory wiring. i coudnlt find the alarm module or the wiring for the alarm i dont know if this is a factory alarm or aftermarket?

does anybody know any tricks for the alarm or where is there somewhere else i should looking for wires?

thanks in advance
