* Around the distributor cap (if equipped): The wires will be connected to the terminals on the cap and then run individually to each spark plug. They'll usually be held in place with clips or routed through designated channels on the engine.
* On the valve cover and engine: The wires will run along the top of the engine, often secured with plastic clips or by the valve cover itself. They follow a specific firing order, which you'd need a repair manual for to trace accurately. Follow the wires from the distributor or coil pack to the spark plugs.
* Under the intake manifold (less likely): In some cases, some sections of wiring might be tucked underneath parts of the intake manifold, though this is less common for the main runs.
To make it easier:
1. Consult a repair manual: A Haynes or Chilton manual specifically for a 1992 Isuzu Rodeo will have diagrams showing the exact routing of the spark plug wires. This is the most reliable way to find them.
2. Use a flashlight: The engine bay can be dark and cluttered; a good flashlight is essential for seeing the wiring clearly.
3. Look for wear and tear: While you're inspecting the wires, check for signs of cracking, fraying, or damage. Worn wires can cause misfires and should be replaced.
If you can't locate them visually after careful searching with a repair manual, it's best to consult a mechanic.
