Hey man, this setup looks good! The only recommendation I would make is to remove your accessory system negative lead or "ground" from the battery and find a good place to ground it out to the chassis. There is a lot of literature of why you don't want to do this on the internet but in short, with the cables going directly to the battery, you run the risk of pulling power from critical systems and efficiency of alternator, and you are now relying more on the main battery ground cable to carry the amps of your accessories as well. Besides that, it looks awesome. great work
