Schematic!

I have a 120A Warn isolator right here. But when running the two batteries (in factory config) they are connected in parallel anyway, so they'd both charge, right?

It also disconnects when IGN is off, so I'm not sure what I'd use the isolator for. On my boat I have an isolator so that the battery that's not connected gets charged, but in the trucks they're always connected when running.

I could certainly steal your idea of running the lights off the AUX battery, but how did you go about that? Did you re-route stuff from the engine-bay side of the fusebox?
