Abstract: A bus bar (20) for grounding multiple wires/cables (74) in an engine compartment of a truck. The bus bar has four threaded studs (24, 26, 28, 30) extending from an outer face of a plate (22) and two circular rings (32, 34) on an opposite face spacing the plate from the dash panel (60). An array of multiple through-slots (24A, 26A, 28A, 30A) in the plate surround each threaded stud with the through-slots arranged in unique circumferential locations about the respective stud to provide unique circumferential locators for a tab (78) of an eyelet terminal (76) on a wire/cable (74) to locate the terminal in a correspondingly unique circumferential location about the threaded stud when placed thereon and in contact with the plate preparatory to tightening of a nut (80) that, when tightened, forcefully holds the terminal against the plate.
