Battery Ground?

On my cuda the big ground went directly to the engine (for the starter draw) and the little one went to the inner wheel well right below starter relay. _ Purpose is to ground everything interior wise so youre instruments dont go searching for ground thru your gas guage or temp guage. Some peeps go from engine to motor mount then jump over the rubber mount to frame side then to neg on battery- I dont recommend it but it does work. You haven't lived until you see your choke cables glow bright red from acting like a ground cable :butthead:
