Bill J,
I'd just by a new or a good used wire harness and set of battery cables for a 1X8/9 series Cub Cadet if you want to move the battery and and voltage reg under the seat. Be a lot easier and cheaper than making your own when you consider your time. The sponsors above can fix you right up. You will have to drill some holes in the tool box pan under the seat for wires to pass through, mount the reg and secure the battery.
