Well for the first time today I felt bad wind under there. My MPG hasn’t budged but I felt what felt like something hitting the bottom of the truck at speeds over 60 and thought a wire was loose slapping my underbody but nothing is. I think the dam not redirecting air is making me feel the gusts through my pedal.Just put Dielectric Grease for electrical connectors in the plug then forget about it. It should water proof it and keep it clean if you ever what to re-attach it.
