I relocated the battery in my DSM, mostly to get rid of all the clutter in the engine bay and doing so made it easier for maintenance. I went to an audio performance store and bought a splitter box that you can put your 1/0 wire into and install the other wires on the other side. It is a very clean install if you do it this way, just make sure the splitter isn't grounded or you'll be in for a surprise. The install itself is really simple and it doesn't require any special tools (maybe a heat gun for the heat shrink and a terminal crimper for a professinal install)
