Updated Diagram 600W Toyota Hiace System

[elpulpo]

Big thanks to everyone who helped me out with my first drawing. I made some updates to the design based on the feedback I got and am much happier with the system. I'm still a bit unsure about my choices for fuses and wire gauges so I may be a bit conservative there. I changed the diagram style hopefully it's easier to read. I expect small loads on this system, about 150-200W continuous load. But it would be nice to accommodate a power tool now and again so peak loads of ~1500 to 2000 W are expected. Please let me know if I missed anything!

Update to this diagram in case anyone else is building a similar system. I adjusted all of my gauges and fuses, I think I've got it just about right.
