    The "Cylinders" and "Coil Connections" are marked above their respective diagrams.
    Yes, you are correct: 3-on passenger's side and 6-on driver's side.
    Relax Steve and take your time!

Firing Order diagram for 2006 Ford Explorer


Hope this helps. The ignition coil:
  • changes low-voltage pulses from the PCM to high-voltage pulses.
  • fires 2 spark plugs simultaneously.
  • has 3 transformers.
    • One transformer fires the spark plugs for cylinders 1 and 5
    • One transformer fires the spark plugs for cylinders 2 and 6
    • One transformer fires the spark plugs for cylinders 3 and 4
Spark plug wires:
  • carry high-voltage pulses from the ignition coil to the spark plugs.
The spark plugs:
  • change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.
The firing order is 1-4-2-5-3-6.
