Alarms are only good for making noise...get a cheap loud alarm for under $250.00 and have a fuel cutoff switch installed somewhere hidden and you won't have to spend over $1200 on a alarm like I did. I got the fuel cutoff switch installed for $50. It disables the fuel pump...only way to steal it is to tow it. BRING ON THE TOW TRUCK thieves...I got a HK .45 waiting 4 ur azz.
