Correct placement of spark plug wires on the distributor results in the correct firing order with gasoline engines using mechanical points. In engines using direct ignition, the engine control unit, a vehicle's on-board computer, ensures the plugs fire in the correct order. Most manufacturers cast the firing order on the cylinder head, valve cover or intake manifold, especially on vehicles with distributors.
Attaching plug wires in the wrong firing order causes rough idle and backfiring. In some cases, the vehicle fails to start.
