Where is the ECM located on a 1997 Chevy pickup truck with 350 engine?

The ECM (Engine Control Module) location on a 1997 Chevy pickup with a 350 engine varies slightly depending on the body style (regular cab, extended cab, crew cab) and options. However, it's most commonly found under the hood, near the firewall, often mounted to the inner fender well.

To be certain, you should:

1. Consult your owner's manual: This is the best source for the exact location.

2. Look for a large, rectangular black box with many wires connected to it: The ECM is usually fairly noticeable once you're looking for it in the general area described above.

3. Check online forums: Search for "1997 Chevy 350 ECM location" on forums like Chevrolet forums or general automotive forums. Pictures often accompany these posts, making identification easier.

Remember to disconnect the negative battery terminal before working near the ECM or any other electrical components to prevent damage or injury.
