* Underhood Fuse Box (Power Distribution Center): This is the larger box and usually located in the engine compartment, often near the battery. Check the area around the battery and along the inner fender well. Your owner's manual should have a diagram showing its exact location.
* Interior Fuse Panel: This smaller fuse panel is usually found inside the vehicle, often under the dashboard on the driver's side. Again, your owner's manual is the best resource for its precise location.
Without your owner's manual: Your best bet is to thoroughly search the areas mentioned above. Look for a plastic box with fuses or circuit breakers inside. It might be covered or have a lid. If you're having trouble, consider searching online for "1992 Dodge RamCharger fuse box location" along with images; this may provide visual clues.
