To replace the dashboard on a 1999 Ram 2500, start by disconnecting the battery and removing any trim pieces, screws, or fasteners securing the dashboard. Carefully detach the instrument cluster and any wiring harnesses connected to the dashboard. Once everything is disconnected, gently pull the dashboard away from the frame, ensuring you don’t damage any components. Install the new dashboard by reversing the removal process, securing all connections and fasteners properly.

In a 1999 Saturn, the fuse for the tail lights is located in the fuse box under the dashboard on the driver's side. Specifically, you should look for the fuse labeled "Tail" or "Tail Lights." If you can't find it, consult the owner's manual for a detailed diagram of the fuse box and its components. Always ensure to replace a blown fuse with one of the same amperage to avoid electrical issues.
