What you are doing is very dangerous if not done properly and you can
burn up your whole van if you make a mistake. You can't just pick and
choose parts of how others have done things without understanding the
issues involved in their choices. 10 gauge wire is not heavy enough
unless you design the system right. Connecting the batteries together
with such small wire should not be done while the starter is operating.
Using a "hot while ignition on" wire to control the relay is a bad idea
because of this but Matsuwesty says that he used battery cable to
connect the relay. Battery cable is not 10 gauge.
