1. Identify the interface and its implementations that need autowiring.
2. Check the `services.yaml` file for existing autowiring configurations.
3. If necessary, enable autowiring and autoconfiguration in `services.yaml`.
4. Ensure the interface is properly type-hinted in the constructor of the class where it's being injected.
5. Clear the Symfony cache to apply the changes.
6. Test the application to verify that the dependency is correctly injected.
