I've got a misfire on the #1 coil on a 4.7 2006 Dakota, swapped coil from one plug to another, issue stayed @ #1.
There are two wires going into coil, one is the power and it's got power coming into coil, where does other wire connect? to PCM ??

 

Other wire will run to the pcm. PCM controls the ground to fire the coil. You really need to be in the Dakota section though.
