    There’s nothing more involved than running a 0 gage wire from your engine battery positive to the new ones positive. From there, you ground out the negative of the new battery somewhere (frame), my ground is done w/ 2 (yes two) 4 gauge wires, I believe. Mine was done by CarToys. I would never recommend them after having to redo most of their work.

    If it's charging you should have more than 14 volts on the second battery when the truck is running
