You MUST find the firing order for your specific engine and year. This information is crucial to avoid engine damage. Here's how to find it:
1. Find your engine's specifications: Look for a sticker under the hood (often near the radiator support) or in the owner's manual. It will list the engine displacement (e.g., 2.8L V6, 2.2L 4-cylinder). The year of your truck is also critical.
2. Use a reliable source: Once you have the engine details and year, search online for "[Your Chevy S10 Year] [Your Engine Size] firing order." Use reputable sources like repair manuals (Chilton, Haynes), automotive websites (like repair manuals), or forums dedicated to Chevy S10s.
3. Look for a diagram: The firing order will be a sequence of numbers (e.g., 1-3-4-2 for a 4-cylinder). This indicates the order the spark plugs fire. The diagram will usually show the distributor cap with the numbers corresponding to the plug wire locations.
WARNING: Connecting the plug wires incorrectly can cause serious engine damage. If you are uncomfortable performing this task, it's best to have a qualified mechanic do it.
