* Under the hood: You'll find numerous control modules (which contain circuit boards) related to the engine, transmission, and other powertrain components. These are often near the engine or firewall.
* Inside the cabin: Circuit boards are inside the dashboard, controlling things like the radio, climate control, and instrument cluster. Some boards might be behind panels, while others might be integrated into the components themselves.
* Under the seats or in the rear: There are boards controlling various electrical systems, including lighting and power distribution.
* In the Body Control Module (BCM): This is a central module containing many circuits related to body functions and is typically located somewhere in the cab or under the dash, often behind panels. Its exact location varies depending on the trim level and specific vehicle configuration.
To find a specific circuit board, you'll need to know *what system* the board is part of (e.g., the ABS system, the power window system, the radio). A wiring diagram for your specific year and model Dodge Ram truck would be essential in locating the correct module and board. You can often find these diagrams online through repair manuals or automotive parts websites.
