The firing order for a 4.3L V6 is different than for either of the V8s. Therefore, I cannot give you the correct spark plug wire order without knowing the *actual* engine displacement (5.0L or 5.7L).
To find the correct firing order, you need to:
1. Verify your engine size: Check the engine block itself (usually a casting number) or your vehicle's documentation.
2. Consult a repair manual: A repair manual specific to your year and engine size will provide the correct firing order and a diagram showing the plug wire routing. Chilton's or Haynes manuals are good options.
3. Look for markings on the engine: Sometimes, the firing order is stamped or marked directly on the engine.
Once you know the engine size (5.0L or 5.7L), I can help you find the correct information, but I need that crucial detail first.
