My '02 alarm goes off constantly for no reason (ie: opening/closing unlocked door. Leaving keys in ignition with car turned off for more than 5 seconds) My factory radio is busted and can't turn the alarm system off via the radio. Is there a wire I can disconnect to just disable it altogether?

I believe the actual problem is my BCU but with the alarm being my only apparent problem id rather just disconnect than a 500$ BCU fix for the time being.

Thanks in advance
