Hey Kevin, the 12 volt accessory circuit of the 4-way to 7-way part # C57672 that you referenced is 12 gauge. What do you plan to power with this circuit?

I would like to be able to charge a travel trailer battery. My plan was to run 10ga wire with a 30amp in-line breaker from the car battery to the 7-pin connector. Would I need to re-wire the adapter with a 10ga wire?

@Kevin Great question but not necessarily. You'd want to run the rest of the wires as 10 gauge for the longer runs since longer wires mean more resistance but just this short section being 10 gauge wouldn't be a problem. Now if you wanted amperage to the battery then yes you would want to rewire it.
