* Many Models: Chevrolet trucks in 1994 came in a wide variety of models (C1500, K1500, Silverado, etc.). The ECM location can differ depending on the model.
* Engine Variations: The engine type (V6, V8, etc.) also influences where the ECM is mounted.
* Specific Year: Even within the same model, the exact location can change slightly from year to year.
How to Find Your ECM:
1. Consult Your Owner's Manual: Your owner's manual should have a diagram or section that shows the location of the ECM.
2. Check Under the Hood: The ECM is usually located in a protected spot under the hood, often near the firewall, or mounted to the engine's inner fender.
3. Look for the Label: The ECM itself will typically have a label that identifies it as the "Engine Control Module."
4. Use an Online Resource: Websites like AutoZone or AllData offer detailed information about vehicle components, including ECM locations.
Important Note: Before you start looking, make sure your vehicle is parked on a level surface and the engine is off. Also, avoid touching any electrical components while the engine is running.
