Where is the ecu in a 2005 Chevy Silverado?

The ECU (Engine Control Unit) in a 2005 Chevy Silverado is typically located under the hood, on the driver's side, often near the firewall. However, the exact location can vary slightly depending on the engine and trim level. It's usually a fairly large, rectangular black box with numerous connectors.

To be certain, it's best to:

* Consult your owner's manual: This is the most reliable source for the exact location of the ECU in your specific vehicle.

* Look for online diagrams: Search online for "2005 Chevy Silverado ECU location" along with your engine size (e.g., 4.3L, 5.3L, 6.0L) for more specific diagrams.

* Check online forums: Silverado owner forums often have discussions and pictures showing the ECU's location.

Be cautious when looking for the ECU; it's usually secured and surrounded by other components. Don't attempt to remove it unless you know what you're doing, as it could damage the unit or other parts of the vehicle.
