not sure bout resetting it and what not....but in the trunk on the left side is where the stock alarm plugs in....i did mine like 3 years go so i kinda forgot....but i know if i closed my passenger door last and locked the car, the alarm would go off in 30 seconds, whether i was out of the car in the car, or driving the car
anyon..in the car, near the fuel shut off switch....left side...there'll be two plugs....unplug one....if the car doesn't start, plug it back in and unplug the other. Can't remember what the other did, but i unplugged the wrong one first.
