* Distributor Cap Variations: The firing order and plug wire placement can vary slightly depending on the specific distributor cap and engine configuration used in your 1981 Chevy 350.
* Engine Orientation: Even for the same engine, the #1 cylinder location and the corresponding plug wire placement can change depending on how the engine is installed in the vehicle (facing forward or backwards).
To find the #1 plug wire location, you need to do the following:
1. Identify the #1 Cylinder: Locate the #1 cylinder on your engine. This is usually identified by a mark on the engine block or a number stamped on the valve cover.
2. Check Your Distributor Cap: The distributor cap should have markings or numbers indicating which plug wire goes to which cylinder.
3. Match the #1 Wire: Find the plug wire connected to the #1 cylinder and match it to the corresponding number on your distributor cap.
Important Note: Consult a repair manual or online resources specific to your 1981 Chevy 350 model for a diagram or detailed instructions for locating the #1 cylinder and plug wire connection.
Remember: Always disconnect the battery before working on electrical components.
