Where is the ecm located on a 1988 Chevy G20 van?

The ECM (Engine Control Module) on a 1988 Chevy G20 van is typically located under the hood, near the passenger side firewall. However, the exact location can vary slightly depending on the engine and other options installed on the vehicle.

To be sure, you should:

* Consult your owner's manual: This is the best resource for the exact location.

* Look for a large, rectangular black box with numerous wires connected to it: This is the most likely candidate for the ECM.

* Check online forums or resources specific to 1988 Chevy G20 vans: Searching for "1988 Chevy G20 ECM location" on sites like forums.chevy.com might yield helpful pictures or descriptions.

Remember to be careful when working near the engine compartment. Disconnect the battery's negative terminal before working on any electrical components.
