Where is the ECM computer located in an 88 Cadillac Eldorado?

The ECM (Engine Control Module) in a 1988 Cadillac Eldorado is typically located under the hood, near the air cleaner housing. However, its exact location can vary slightly depending on the specific engine and options. It's often mounted to the inner fender well or firewall in that general area.

To be certain, you'd need to:

* Consult your owner's manual: This is the best source for the exact location of all major components.

* Look for a rectangular black box with numerous wiring connectors: This is the typical appearance of an ECM.

* Trace the major wiring harness: The harness leading to the engine and various sensors will often lead directly to the ECM.

Be aware that working near the engine is hot and potentially dangerous. Let the engine cool completely before working near it.
