Based on my research there should be a pink 30 amp fuse located at the F30 position inside the power distribution center under the hood of your 2016 Ram 2500. This fuse is connected to the 12V power circuit on the factory 7-Way so you will want to make sure this fuse is present and in good condition.

Please just let me know if you still don't get power at this pin after replacing the fuse and I will be happy to look into this further.

I want to isolate the truck from the trailer, with lithium batteries now in the rv, the power goes backwards from the rv to the truck since the charged voltage of lifepo4 is 13.4v pls solar constantly charging it....would taking this fuse out cause any other issues i should be aware? Thanks
