Hello there. I'm attaching the image that I think you need. Hopefully this gets you going again.

Tip: the best way to avoid this situation when doing spark plugs and wires is simply do do it one cylinder at a time. This helps you too keep things organized and straight while avoiding confusion.

Good luck and let us know if this helps out if you need more help with your truck.
