Installation Guide

1. Safety First: Ensure the engine is off and cool to the touch. Disconnect the battery.
2. Locate Wires: Identify the spark plug wires connected to the spark plugs and distributor cap.
3. Remove Old Wire: One at a time, grasp the boot firmly and twist gently to pull it off the spark plug. Then, disconnect the other end from the distributor cap. Note its path.
4. Install New Wire: Route the new wire along the same path. Firmly press the boot onto the spark plug until you feel it click into place.
5. Connect to Distributor: Attach the other end to the corresponding terminal on the distributor cap, ensuring a secure connection.
6. Repeat: Repeat the process for all remaining spark plug wires, replacing them one by one to avoid mixing up the firing order.
7. Final Check: Once all wires are installed, double-check that each is securely connected at both ends. Reconnect the battery and test the engine.
