The ECM (Engine Control Module) in a 1992 Chevy Lumina is typically located
under the hood, on the passenger side of the engine compartment. However, its exact position can vary slightly depending on the engine type and specific trim level. It's often attached to the inner fender well or firewall. It's usually a fairly large, rectangular black box with many connectors.
To be certain, you should:
* Consult your owner's manual: This is the best resource for the precise location in your specific vehicle.
* Look for a large black box with wiring harnesses: Systematically check the passenger side of the engine bay.
Be careful when inspecting the area, as parts of the engine compartment can be hot.
