It turned out to be the light set. Would not work with either my Vegas OR my Ford Explorer! Picked up a different set of lights (a little higher priced) and plugged them in...no problems! Wonder what is in that set of lights that it liked Subarus and Chevys but not Fords!

It doesn't exist in the '18, kind of a nice addition by Thor.
