No wiring diagram

[Waterloo]

I have added two separate circuit panels/boxes in my truck. I would do it as it really cuts down on the wiring mess, and you will not have to worry about running out of room or getting creative and causing even more issues. Each panel in my truck is running direct from the battery, each have their own grounds. No issues to date, and they filled up quickly. So, if you think you will need 5 circuits, I would get a box that can handle at least 12.
