Question
I have a 98 DeVille that i have recently put an after market stereo into. my alarm comes on when i try to start my car. how do i fix this, and where is the fuse for the alarm system so i can disable it until i do get it fixed?
hello,
You did not state if you were refering to an after market alarm or a factory installed alarm.
If the headlights are flashing and the horn is sounding, this is a factory alarm problem and you installed the stereo into the factory wiring for the factory alarm.
Its so common that people think there is no big deal to disabling the factory alarm just by removing a fuse. It is not that easy and it is common to find many different circuits wired into the factory installed alarm system.
Its all to common to find if you can disconnect the alarm fuse, so many other things will not work as well.
If you are looking for the location of this fuse, the owners manual may tell you where it is located.
If you are hearing a siren or the parking lights flash, you are dealing with an after market system. If you look under the driver's dash after you remove the black plastic hush panel, you should see the after market alarm module. Either disconnect it or remove the in-line power fuse.

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
