When wiring spark plugs for a vehicle, it’s important to understand how the firing order of your engine works. Luckily, the Chevy 350 engine has an easy-to-follow firing order: 1-8-4-3-6-5-7-2.

This diagram shows each spark plug's corresponding cylinder number and its respective connector color. As you can see, each spark plug is linked to its cylinder with a specific color coding. For example, the top spark plug (cylinder 1) is connected to a yellow wire, while the bottom one (cylinder 2) is connected to a green wire.

In addition to connecting the spark plugs to their respective cylinders, you also need to attach ground wires to each spark plug. The ground wires are usually black in color and are attached near the spark plugs. You’ll need to locate the ground wire for each spark plug and connect it securely.

Finally, be sure to double check all your connections before starting the engine. Inspect the wiring diagram one more time to ensure that all the spark plugs are connected to the correct cylinder and that the ground wires are secure. Once you’ve made sure everything is correct, you can start your engine and be on your way!
