Where is the control module for air bags located on a 1999 Ford Ranger Four Wheel Drive Extended Cab?

The airbag control module (ACM) in a 1999 Ford Ranger four-wheel-drive extended cab is typically located under the dashboard, on the driver's side. However, it's not always in the exact same spot across all vehicles. It might be behind a panel, sometimes near the steering column.

To find it, you'll likely need to:

1. Consult a repair manual: A Ford Ranger repair manual specific to the 1999 model year will have a diagram showing the exact location of the ACM. This is the most reliable method.

2. Carefully remove lower dashboard panels: This will require some patience and possibly some specialized tools. Be extremely careful not to damage any wiring. Start by removing the panels around the steering column, working your way towards the center of the dashboard.

3. Look for a rectangular black box: The ACM is usually a relatively large, rectangular black box with several connectors. It might have labels or identifying markings.

Important Safety Note: Disconnecting or working on the airbag system is dangerous and can lead to accidental deployment. If you're not comfortable with this type of work, it's best to take your truck to a qualified mechanic or dealership for any repairs or diagnostics involving the airbags. Even just locating the module carries a risk if you're unfamiliar with automotive electrical systems.
