The two batteries should be wired in parallel so you still only have twelve volts. The starter is a twelve volt unit so there is no special wiring involved. Basically you have the same wiring as a single battery, just two connections for each instead of one.
I cannot find a good schematic of it as it was not sold in the US as a diesel just a gas model.
