if you know car audio it easy for you to make you needs some awg4 power amp cable, inline fuses (60+amps) and a 100amp relay with bolt on posts. sometimes you can buy the power cabling from local car audio shops for power amps if you cant get the cables try a set of jump leads and cut the ends off as well capable of powering the current and cheaper to buy, maplins do the fuses if your stuck

ok you connect you powercable from van battery to a fuse then to relay, on the other opposite relay post you then run your cable from relay to leisure battery but put a fuse in near the leisure battery, so you have both leads fused by both batteries, then you have two posts left on relay, you then earth one post to body etc and the last post is your trigger wire normally taken from the blue trigger wire on the alternator.
Make sure you also have a good earth big cable etc on leisure battery as it can pull a lot of current when flat like 60+amps

also if you plan on running a car audio amp you should also add an extra earth back to van battery from the chassis as a 1200 watt car amp can pull 100amps on it own and the original earth straps aren't really able to handle the current on the standard cabling
