yep it came with a grounding wire and i attached it and made sure it's a good connection. the only thing that was wierd or made me thing i may have hooked it up wrong is it's different that the last underbed tank kit i bought. like i said the last one had a threaded stud for the wire, this one just had a odd nub on top. i am not sure what kind of connector it is supposed to have so i used a crimp connector. i am draggin' my heals on dropping the tank, busy painting the bed for now. mabey the light will dawn on what i did wrong. i was hopin' someone could tell me "oh if the gauge goes to empty when you turn on the key it's bla bla bla" . i was wishing for the lazy way out. hr
