Where is the theft control module located?

It's internal of the Body Control Module.

I hope you are aware, that even when you replace that part, the vehicle is not going to run. the vin number of the modules has to match, the key, which on Dodge is going to be referred to as a skim, that has to be reset. so a skim reset gets done, then the vin gets programmed into the modules, otherwise, it will crank, but will not run.
