Hi
The anti-theft alarm is pretty well integrated into the whole vehicle. The switches used for the alarm for example are needed for the central locking and interior lights for example, and the control module for the alarm is the body computer (AAM), so you can't just disconnect the control module, as it isn't a seperate part.
In addition, it may be difficult to install a remote start as the the truck has a Driver Authorization System integrated into it, it can't be disables as it involves the engine control module. And I don't believe one of these "key holder boxes" like is used with other vehicles will work as the system uses a rolling code.
What specifically do you need to know about the alarm?
