So the American Modified plug and play harness is apparently NOT water tight. The ford plugs coming off of the lights got corroded to the point where they shut off my high beams - permanently, and then I'm thinking for some reason messed with the plug enough that the marker lamps in between the high and low beams would stay on for 15 mins or so after the truck was off. My dealer, rightly so I guess, did not cover this under warranty, but did get the issue fixed by installing new plugs on the headlights and connecting as done from the factory. The AM Grille lights are still installed, but not connected to anything. I suppose shame on me for not applying dielectric grease at the get go, but the OEM connections didn't have it so i figured it should be good. Now on to fight with AM to see if i can get any sort of warranty out of them.
