I recently relocated my battery to behind the cab and was worried I would need 0 gage or that the cable would be too long. All my local Napa had in stock was 2 gage. The 2 gage works great! The total length of the cable is probably 7-8 feet. The motor spins over fast and fired up quick. I was amazed how easy it fired since my truck has been sitting for more than six months.
