To find the correct wiring order, you must identify your engine's displacement (e.g., 5.7L, 7.4L). Once you know the engine, you need to:
1. Consult a repair manual: A factory service manual specific to your year and engine is the best resource. These manuals have detailed wiring diagrams. Chilton's or Haynes manuals are also good options, but the factory manual is most accurate.
2. Use an online wiring diagram resource: Some websites offer wiring diagrams, but make sure the site is reputable and the diagram matches your specific engine. Always double-check the information against a trusted source.
3. Look at the distributor itself: Sometimes, the distributor cap will have a firing order diagram molded into it, or the wires may be labeled. However, this is not reliable for accurate wiring order.
Without knowing the engine size, any wiring order I provide would be inaccurate and potentially damaging to your vehicle. Providing the wrong wiring order could cause misfires, engine damage, or even a fire. Please find your engine's displacement and consult a repair manual for the correct information.
