On a 389 Peterbilt, the dash light fuse box is typically located behind the dashboard, accessible from the driver's side. You may need to remove a panel or cover to reach it. Additionally, a secondary fuse box may be found under the hood or near the battery, depending on the specific configuration of the truck. Always refer to the owner's manual for precise locations and diagrams.
