run the power from the battery to the switch then from the switch to the bar. Just buy a good switch.My center post has no voltage whatsoever. I was thinking about running a separate power bus bar and attaching the accessory grounds to the chassis. My only problem is I want this to be switched and a direct feed from the battery will be hot all the time.
I want the new bar to be ig option switched, like the factory bar. I guess I'd need a relay for the bar?
