In a 1990 GMC S15 with a 2.5L engine, the Engine Control Module (ECM) is typically located under the dashboard on the driver's side. It is usually mounted above the brake pedal or near the steering column. Accessing it might require removing some panels for better visibility and reach. Always ensure to disconnect the battery before working on the ECM.
