We bought an enclosed 7 X 12 cargo trailer to haul the Tri-Glide on longer trips.
The trailer has a 7 pin plug due to having electric brakes, tow vehicle has both 7 pin and 4 pin.
I want to take 12V into the trailer to keep battery charged.
I have 2 options. Pick up 12V off of the 4 pin to maintain the battery or tap into the 12V supply for the trailer lights etc.
I don't see an issue with either option but want to make sure I am not missing something.
Thanks
