Where is the electronic control module for a 1994 Mazda 929?

The Electronic Control Module (ECM), also often called the Powertrain Control Module (PCM) in vehicles like the 1994 Mazda 929, is typically located under the hood, near the firewall. However, the exact location can vary slightly depending on specific model options.

To pinpoint its location for your specific 1994 Mazda 929, I recommend:

* Checking your owner's manual: This is the best resource, as it will have a diagram showing the location of major components under the hood.

* Looking at online forums: Search online forums dedicated to Mazda 929s (like ClubRoadster.net or similar forums). Someone may have posted a picture or description of its location.

* Using a wiring diagram: If you have access to a wiring diagram for your car, the ECM will be clearly shown.

* Consulting a repair manual: A Haynes or Chilton repair manual for your vehicle will likely contain detailed information and diagrams.

Keep in mind that the ECM is usually a relatively large, black rectangular box with numerous connectors. It might be attached to the firewall or secured to a bracket nearby. Be cautious when looking for it, as you'll be working near hot components in the engine bay.
