Where is the ECM located in a 1990 chev?

In a 1990 Chevrolet vehicle, the Engine Control Module (ECM) is typically located under the dashboard on the driver's side, near the steering column or behind the glove compartment. In some models, it may also be found in the engine compartment, mounted on or near the firewall. To access it, you may need to remove some panels or components. Always refer to the specific service manual for your model for precise location details.
