I have an 'Itaco" Car alarm in my Corolla. It was set off in a car park just after i armed it. When trying to turn the alarm off with the keypad nothing worked i got pissed off ,popped the bonnet and tore the wires out off the loudspeaker(I now know that how to use the valet switch whitch would have solved my problem) I now want to reconnect it but everytime i connect the wires the alarm is set off even the valet switch doesnt work. Help would be appreciated
