It seems that because the diagram for the fuse codes aren't located in the owners manual, it would be a dealer item only. One possible solution is to buy an assortment of fuses.. maybe (15) switch them out 1 by one.

If you are looking for the fuse box diagrams or any other diagrams for your Ram, check promanuals.net for a factory service manual for around 20 bucks or so. It's an invaluable tool for my Ram 2500.
