Tools You'll Need:
* Phillips head screwdriver
* Flathead screwdriver (possibly, depending on your car's specifics)
* Wire cutters/strippers (if necessary for new wiring)
* Socket set (might be needed depending on the securing method of the ignition switch)
* New ignition switch (ensure you get the correct one for your model)
* Pen and paper (to make notes of wire connections)
Steps:
1. Disconnect the Battery: This is crucial to prevent electrical shocks and short circuits. Disconnect the negative (-) terminal first.
2. Remove the Steering Column Shroud: This usually involves removing screws located under the steering wheel and/or around the column. Consult a shop manual specific to your 1967 Mustang for exact locations. The shroud is the plastic or metal piece that covers the steering column.
3. Access the Ignition Switch: Once the shroud is off, you'll have better access to the ignition switch. Its location varies slightly depending on the model and whether you have an automatic or manual transmission. The switch is usually mounted on the steering column itself. You might need to remove other components like the steering wheel (difficult and generally not recommended unless absolutely necessary) or other parts to fully access the ignition switch.
4. Disconnect the Wiring Harness: This is the most crucial step. Before disconnecting anything, carefully draw a diagram or take pictures showing which wire goes where. The wires are usually color-coded, but double-checking is essential. Note the color and position of each wire. Gently disconnect the connectors from the ignition switch.
5. Remove the Ignition Switch: This might involve removing screws or nuts holding it in place. Some switches are held in with a retaining clip. Again, your shop manual will be crucial here. The switch itself might be a cylinder or a more rectangular unit. Remove it carefully, taking note of its orientation.
6. Install the New Ignition Switch: Carefully install the new ignition switch in the exact same orientation as the old one.
7. Reconnect the Wiring Harness: This is where your notes and pictures become invaluable. Carefully reconnect the wires to the new ignition switch according to your diagram. Double-check everything before proceeding.
8. Reinstall the Steering Column Shroud: Put the shroud back in place, securing it with the screws you removed earlier.
9. Reconnect the Battery: Reconnect the negative (-) battery terminal.
10. Test the Ignition System: Turn the key to test all the ignition functions (lights, starter, accessories).
Important Considerations:
* Shop Manual: A 1967 Ford Mustang shop manual is highly recommended. This will give you detailed diagrams and instructions specific to your vehicle's model and options.
* Professional Help: If you're uncomfortable working with automotive electrical systems, it's best to seek professional help from a mechanic. Improper wiring can damage your car's electrical system.
* Key Compatibility: Ensure your new ignition switch is compatible with your existing keys. You might need to have your keys re-keyed or get new ones if you replace the switch with a non-matching one.
This is a general guide; specific steps may vary slightly based on your Mustang's trim level and other factors. Always consult a repair manual for your specific year and model. Incorrect installation could lead to electrical problems or even damage your vehicle.
