The dark green/orange wire is the power feed.

This is how I diagnosed my 5.4 liter coil packs, I isolated the cylinder that was misfiring and then took a know coil from a good cylinder and swapped with the suspected bad coil. When the misfire went to the specific cylinder I swapped, I replaced that coil. Note- It is advised to replace all coil packs if you can afford too!
