To find the correct spark plug wire order on your specific coil pack, you need to:
1. Consult your Ford Explorer's owner's manual: This is the most reliable source. The diagram should clearly show which cylinder each wire connects to.
2. Use a reliable online repair manual: Sites like Chilton or Haynes offer detailed diagrams. Make sure you specify the exact year and engine size.
3. Look for markings on the coil pack itself: Sometimes there are faint markings or numbers on the coil pack that correspond to the cylinder number.
Do not rely on generic diagrams or information found on less reputable sites. Incorrectly connecting the spark plug wires can seriously damage your engine. Always double-check your work.
