Things Change.. Butters is now getting a 392

That is a lot running on a 30A fuse. I think I have a 25A on 2 fans. I think I'd rather the fuel pump and fans be on a circuit with a relay and independent fuse. Also think you're on the right track with the fuel pump first. As I'm sure you know as the flow increases on a pump, so does the current. That would explain the fuse popping when you get on it.
I was working with Blake on it last night, just to get a grasp of how that panel is laid out. With this panel, the ecm is what kicks the fan relay and uses a oem fan harness. The fuel pump is just ignition on, so it'll be easy. I can do one of two things with it.. use the fuel pump output from the Sublime panel as a relay trigger or ignition switch to trigger it .
