there's several of them on that truck, i own two of those mine has one from the cross member to the chassis, and one from the frame to the body,and in front it has one from the body to the frame,look for any braided wires on that one,i don't know if someone installed all the ones on mine or not but it has about 5 all together,all ranging from the body to the frame,i have no problems though with charging or anything being grounded,there's also one from the bumper to the body on mine,good luck.
