The ignition module itself is a small, relatively easily accessible box. To replace it:
1. Locate the Ignition Module: Consult your Ford Ranger's repair manual (Haynes or Chilton manuals are good sources) to pinpoint the exact location of the ignition module. It's usually a black box near the ignition switch, under the dash.
2. Disconnect the Battery: This is crucial to prevent accidental shorts and electrical damage. Disconnect the negative (-) terminal first.
3. Access the Module: You might need to remove some dash panels or trim pieces to gain access to the module. Work carefully to avoid damaging any plastic clips.
4. Disconnect the Wiring Harness: Carefully unplug the electrical connectors from the ignition module. Take pictures or make a diagram before disconnecting to ensure you reconnect everything correctly. Label wires if necessary.
5. Remove the Ignition Module: The module is usually held in place with screws or possibly a retaining clip. Once these are removed, you can take the module out.
6. Install the New Module: Install the new ignition module, ensuring that it's securely fastened.
7. Reconnect the Wiring Harness: Reconnect all the electrical connectors to the new module, carefully matching them to their corresponding locations based on your pictures or diagram.
8. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
9. Test the Ignition System: Start the engine to verify the new ignition module is functioning correctly.
If you're still seeing rivets and having trouble finding the module:
* Double-check your repair manual: Ensure you're looking in the correct location. Diagrams and pictures are invaluable.
* Search online forums: Specific Ford Ranger forums (like those on sites dedicated to classic Ford trucks) often have detailed threads and pictures related to specific repair procedures, including ignition module replacement.
* Consider professional help: If you're uncomfortable working on your vehicle's electrical system, a qualified mechanic can quickly and safely replace the ignition module.
Remember, safety first. If you're not comfortable working on your vehicle's electrical system, it's always best to seek professional assistance. Working with automotive electronics can be dangerous if proper precautions aren't followed.
