Tools You'll Likely Need:
* Socket set and wrenches: Various sizes will be needed.
* Screwdrivers: Phillips and flathead.
* Wire strippers/crimpers: If you need to replace any wires.
* Test light or multimeter: To verify wiring connections.
* Repair manual: Absolutely essential for specific instructions and wiring diagrams.
* New ignition switch: Ensure you get the correct replacement for your model.
General Steps (Consult your repair manual for precise details):
1. Disconnect the battery: This is crucial to prevent electrical shocks and short circuits. Disconnect the negative (-) terminal first.
2. Remove the steering wheel: This is often the most challenging part. You'll likely need a steering wheel puller (rentable at most auto parts stores) and the correct size socket for the steering wheel nut. Mark the steering wheel's position relative to the steering column before removal to ensure correct reinstallation and proper alignment.
3. Access the ignition switch: The ignition switch is usually located on the steering column, beneath the steering wheel. This often requires removing the steering column shroud or other trim pieces. Your repair manual will detail how to access it on your specific model.
4. Disconnect the wiring harness: Carefully disconnect the wiring harness connectors from the ignition switch. Take pictures or make detailed notes of the wiring connections before disconnecting. This is crucial for reassembly. Use a labeled diagram from your repair manual to assist you.
5. Remove the ignition switch: Once the wiring harness is disconnected, you'll need to remove the switch itself. This usually involves removing screws or bolts that secure it to the steering column. Again, your repair manual will give you the specifics.
6. Install the new ignition switch: Carefully install the new ignition switch, ensuring it's securely fastened.
7. Reconnect the wiring harness: Reconnect the wiring harness, carefully matching each wire to its corresponding terminal as noted in your repair manual or your earlier diagrams/notes. Double-check every connection.
8. Reinstall the steering wheel: Reinstall the steering wheel, ensuring it's aligned correctly. Tighten the nut to the manufacturer's specified torque.
9. Reinstall the steering column shroud and trim: Put everything back together.
10. Reconnect the battery: Connect the positive (+) terminal last.
11. Test the ignition switch: Turn the key to verify that all functions (ignition, accessories, starter) work correctly.
Important Considerations:
* Wiring: The wiring in a 1964 Mustang is different from modern cars. Miswiring can cause serious damage. A wiring diagram is indispensable.
* Lock Cylinder: The lock cylinder might be integrated with the switch or separate. Your repair manual will clarify this. You may need to transfer the lock cylinder from the old switch to the new one.
* Professional Help: If you're uncomfortable working on your car's electrical system or are unsure about any step, it's best to consult a qualified mechanic. This repair can be challenging for those without experience.
This is a general guide. A detailed repair manual specific to your 1964 Mustang is essential for successful completion. Failure to follow the correct procedure can lead to damage or injury. Be methodical, take your time, and refer to your manual frequently.
