How do I find the alarm module on a 2003 Dodge Caravan SE? - se more condition_symptoms

I changed the battery and cables into the trailer, and then the car will not start.
The dealer told me to find the alarm module and to carry them out should be arranged in the vicinity of the engine, I do not know where or how can I do to start the caravan. Ideas?
