Battery charge wire on 7 pin plug

[awaywego]

On the 2019 1500 Longhorn, is there a travel trailer battery charge wire running back to the 7 pin plug? (regardless of what tow package options might or might not be purchased with the truck).

And is that trailer battery charge wire run through a factory-installed battery wire isolation relay so the charge circuit to the travel trailer is off when the truck is off?

Thanks

Yes there is a charge wire for the battery. Pin number 1.

Thanks for that info. Do you know if the charge to the trailer is stopped when the truck is turned off? Some trucks and SUVs do this, and some don't.

Not 100% sure,
