Eez Moose, are you having a problem with your battery? If not, why worry about a charge line. I’ve pulled our V6 for over 30k miles with no charge line. Not sure if the new procedures on the 4cyl leave the electric power steering powered or not. IF the principle is to leave power to the electric power steering, a battery disconnect would invalidate the instructions.
