The Engine Control Module (ECM) on a 1998 Oldsmobile 88 is typically located under the dashboard, on the driver's side, near the steering column. You may need to remove some panels to access it fully. It's often mounted on or near the firewall, making it somewhat difficult to reach without proper tools. Always ensure the vehicle is off and disconnected from the battery before attempting to access the ECM.
