Expert Reply:
The fuse for the 12-volt accessory circuit feed to the 7-way is a 30 amp fuse in location F30 in the fuse box in the engine compartment.
Keep in mind that due to the distance between the alternator on the tow vehicle from the trailer battery and the small wire gauge used in that circuit limits the amount of amperage that can be delivered on that circuit. You can maintain a battery but there won't be enough available amperage to charge a depleted trailer battery.
If shore power is available, you can use a battery charger like # CTEK56353 to completely charge the battery. Another alternative would be to use a DC to DC battery charger like the Redarc # RED46FR to completely charge the trailer battery using the tow vehicle's alternator as long as the vehicle is running.

is the wiring for the trailer 12v aux line hooked up from factory on the 2015 dodge ram 3500? On my GMC Yukon it was tucked in near the batter tray but I had to hook it up.
