There isn't a module specifically called a "RAP module" in a 2000 Ford Excursion (or most other vehicles). RAP usually refers to
Remote Anti-theft Perimeter system. The functionality of this system is spread across several modules, primarily the
body control module (BCM). The BCM integrates many vehicle functions, including the alarm system.
Therefore, you won't find a single "RAP module." The BCM itself is usually located under the dashboard, but its precise location can vary slightly depending on trim level and options. You'll likely need to consult a wiring diagram or a repair manual specific to your 2000 Ford Excursion to pinpoint the BCM's exact location.
