The connection to the battery is something that many people have reservations about until they actually start the process and realize that it is not so bad. There are different ways you can get to the battery and we actually wrote an FAQ article on this topic which I have linked for you. The FAQ gives general tips on different methods for routing the power wire.
You can run the wire through the vehicle if you wish but just keep in mind that this does take more time and you may end up needing additional wire because you will not be routing the wire in a straight line.
As far as mounting the 4-Way end under the vehicle, that, too, can be accomplished though there is some extra work involved and you may have to drill through the bottom of the vehicle. You would need to remove as much flooring as you can from the cargo area in the van, getting down to the bare metal. At this point you would need to locate a grommet or other opening through which you can route the wiring. However there is a good chance any grommet you find will not be large enough to accept the 4-Way.
You would have to cut the wires leading from the converter box to the 4-Way then route the cut end through the grommet, seal up the grommet, and reattach the wires to the converter. Or you can use a hole saw to cut a large enough hole so you do not have to cut and splice the wires. If you must drill you will need to be aware of what is on the other side of the drilling location and you will have to find some way to seal up the hole like a rubber plug and sealant obtained locally.
