You may not want to disconnect the alarm system. It is connected to many other area's within the vehicle for thieft protection. If your alarm goes off when the car is not in use at various times during the day then that is another issue. I visited the dealer today and prodded the mechanic with a bunch of questions. The main reason for the alarm to trigger in most cases is the sensor in the trunk lid. You have to take off the covering on the inside of the trunk lid. There should be two wires. One should be for the trunk lid to open electronically the other for the alarm system. (Sorry I don't know which wire is for what function). If it is possible to disconnect one at a time to determine it's functionality, then try that. If you like to take chances, disconnect both wires. The only real problem you would encounter is that you would have to use your key to open the trunk instead of opening it with the FOB. I haven't tried any of this yet but I will be giving it a try real soon. If you choose not to go this route the cost of running dionostics and getting it repaired is about $85 at the dealership.
What is your problem? Is it because the alarm goes off for no reason? If it is I had the same problem and can help you.
Yes, cut the red wire.
How car i disconnect the alarm system of Nissan quest 2005. Disturbing the neighbours
Something wrong with your alarm system, like not working maybe.
The likely reason why the alarm in a 1999 Lincoln Continental goes off on hot days is because warm air flow triggers the sensors. You can deactivate the alarm by unlocking the car.

Disconnect the alarm horn !
If you have a remote that locks & unlocks your antitheft system it could be as simple as resetting your remote, I had a similar experience.
The factory alarm is built into the Body Computer. It is not possible to unhook it.
Some alarms systems have a protection function which will prevent starting the engine is somebody tried disconnect the battery and connect it again. Also what might happen is that your alarm system doesn't have memory in the case if you disconnect the battery. Thus, if you do disconnect the battery it will reset the alarm system to the default factory settings. By default, the alarm system will block starting the engine.
There is no individual alarm fuse. The alarm is built in with the body computer.
