Power to trailer when engine is off

[Mosey]

Hi all,

I pull a 16 foot enclosed trailer that has switched interior lights. It has a seven pin connector which supplies power to the interior lights. This works great when the engine is running or in accessory mode, but when off I get no power. My previous truck (Canyon) would supply power even when off. Is there a setting that will power the trailer with the engine off?

Thanks.

Yes, I’d like to find a solution to this also, PITA when the lights go out while inside!
