I'm cool with the clean look. I have no problem cutting the box. If that method works well for you too, we are good.Ok guys, the last piece of this is indeed the 1/0 routing. I know the way I wanted to route the cable but its turning out not be a very efficient way to go. I wanted to rout the cables to the back of the battery tray and have them follow the same path as the existing ground cables to the battery. But in doing so it means that some cutting of the battery tray is necessary. I did it on mine but there is a substantial portion that needs to be cut to have the cable routed and I really don't like having to chop up the battery box. This means bringing the 1/0 up to the battery from the front which aesthetically is unappealing but gets the job done. The other cable can be routing on the side of the battery tray to the block. Thoughts before I start chopping cable?
