Welcome! I'm not one for towing so I've never tried it, but I can give you my two cents from reading a lot.
For fuel, it's honestly fine to just use the manufacturer suggested octane. In most cases, using higher octane doesn't do much of anything for performance. As for towing, I'd assume the wiring is for brake lights on your trails and whatnot.
