I have the factory tow package installed on my 2017 Pilot. I've read that one of the wires might not be hot from the factory. The wire I'm referring to would be the one that would charge the battery in my popup while towing. From what I understand in some vehicles you have to run a separate wire directly to battery to achieve this. So what I'm asking basically is if I turn my popup refrigerator on to pre cool on 12v while towing to destination will the factory wire harness provide the power needed to charge the popup battery in the camper? I have a power lift roof on my popup and don't wanna end up with a dead camper battery when I arrive to setup.
