Need help determining fuse position for towing plug to charge battery on trailer. I have a dump trailer and need the battery charged while towing. I have had other vehicles that have this feature and have had to stick fuse in the fuse box for this feature to work, my Durango has factory tow package. Need help to find position in the fuse box to check this out. Thank you in advance!

I gave this a look and I still am confused. I even called a Dodge service department and they said it does not charge trailer battery. I see from the above descriptions that the 7 way harness does have power function. So I think it does have this ability. Just need someone with first hand experience. Thanks

 

Dunno. Never heard of that as a function.

 

its for trailers with electric brakes....or winches on trailers where there is a battery.
