Challenges:
* Different Ignition Systems: The 1967 system is entirely mechanical (points, condenser, coil), while the 1979 system is electronic (likely using an ignition module, coil, and possibly a crank sensor). They are not directly compatible.
* Wiring Harness: The 1967 harness is not designed for the electronic ignition system. You'll need to adapt the wiring.
* Power Supply: The electronic ignition system requires a consistent, clean power source. The older system might not provide this.
* Grounding: Proper grounding is crucial for electronic components. Ensure a solid ground connection for the ignition module.
* Distributor: The 1979 distributor is likely different from the 1967 one, potentially requiring modifications to the distributor gear or the oil pump drive.
Steps to get the electronic ignition to work:
1. Identify the Ignition System: Determine the exact type of electronic ignition system in the 1979 engine. Is it a DuraSpark system (common in many Fords)? Knowing the specific components (module, coil, etc.) is essential.
2. Wiring Diagram: Obtain a wiring diagram for both the 1979 engine's ignition system and the 1967 truck's original wiring. Compare them carefully to identify what needs to be adapted.
3. Power and Ground: Ensure you have a clean, reliable 12V power source for the ignition module. This often requires running a new wire from the battery or fuse box. A solid ground is equally important.
4. Ignition Switch: The 1967 ignition switch might not provide the correct power or signal for the electronic system. You might need to either adapt the existing switch or use a relay to control the power to the ignition module.
5. Distributor: Make sure the distributor is correctly installed and timed. This is critical for proper engine operation. You might need a timing light to set the timing correctly.
6. Coil: The coil is likely different. The 1979 electronic ignition uses a specific coil designed to work with the module. Make sure you have the correct coil.
7. Wiring Adaption: Carefully wire the ignition module according to its wiring diagram, connecting it to the power source, ground, distributor, and coil. This step requires precise attention to detail to avoid short circuits or incorrect operation. You'll likely need to splice wires, use connectors, and potentially add new wiring.
8. Testing: Test the system thoroughly. Start with a basic visual inspection of all connections and then try starting the engine. Check for spark at the distributor cap. Use a multimeter to verify voltage and ground connections.
Recommendations:
* Professional Help: This is a complex task, and unless you have significant electrical and engine experience, it's strongly recommended that you seek professional help from a mechanic experienced with classic car restorations. Improper wiring can damage components and even cause a fire.
* Wiring Harness Kit: Some companies specialize in wiring harnesses designed for engine swaps. A kit could simplify the wiring aspect.
* Online Forums: Search online forums dedicated to classic Ford trucks or engine swaps. Other enthusiasts might have tackled this specific conversion and can provide valuable advice.
Without knowing the exact engine and truck models, providing more specific wiring instructions is impossible. But this outline should give you a good starting point. Remember, safety first! Take your time and double-check everything.
