OEM ground wire was riveted to headlamp housing.
Works only if current path through mounting stud and multiple levels of paint and/or rust is adequate.
I always install internal star washers between sheet metal, reinforcement plate, etc.
I also run individual ground wire to rear lamp as ground connection through fender/axle trumpet is exceptionally unreliable.
