There isn't a single definitive diagram for the distributor cap wire placement because the cap itself can be rotated. However, the order of the terminals in the distributor cap *relative to each other* is consistent.
To determine the correct placement:
1. Identify the #1 cylinder: This is usually the front-most passenger side cylinder. Consult your owner's manual or a repair manual for a visual illustration. Many online resources also provide diagrams of the engine.
2. Locate the rotor: The rotor inside the distributor cap points to the spark plug wire that's about to fire. With the engine at its #1 cylinder firing position (you'll need to rotate the engine to achieve this), the rotor should point to the terminal for cylinder #1.
3. Follow the firing order: Once you've identified the #1 cylinder terminal, proceed to connect the remaining wires in the 1-5-3-6-2-4 firing order, going around the distributor cap sequentially.
Important Considerations:
* Numbering on the Distributor Cap: The distributor cap itself *might* have numbers on it corresponding to the cylinders. If so, this makes the process much easier.
* Professional Assistance: If you're not comfortable with this procedure, it's best to seek help from a qualified mechanic. Incorrectly wiring the distributor can damage your engine.
In short, you *must* start by visually identifying cylinder #1's location, then using the firing order and rotor position to correctly wire the distributor cap.
