DO these trucks have the soy wiring?? God I HOPE not!!!! I have a couple of "regulars" at work that I deal with that issue. usually the same area Ive repaired previously. but those are Fords. and a couple Chevy Caprice cop cars. On the Chevys they like the plug wires (easy fix at least) on the Ford trucks the gas tank is line a shelf for them to sit on and harvest the wiring along the driver side of frame. Besides that, they love the coil and fuel injector wiring on top of the engine/ last cyl on driver side. #7 on Chevy or Dodge but same hole is #8 by Ford cylinder numbering.

 

My 2011 actually did the same thing a few years ago. I was driving in some ice/snow at the time. It also went away on it's own. Think it also said Bank 2
