Do you ever use your trailers behind 12 volt vehicles? If not, then wire them to be compatible with the 6 volt positive ground electrical system in your Power Wagon.
If you do use your trailers with 12 volt vehicles, AND your 12 volt trailer does NOT use dual filament bulbs with offset nipples to orient them in their sockets, but instead uses separate single filament bulbs for trailer lights and brakes lights that have straight line opposite nipples, then just change out all the bulbs, including side marker lights, in your trailer to 6 volt single filament bulbs whenever you use it with your Power Wagon.
If your trailer uses 12 volt dual filament bulbs with offset nipples for its rear, turn and brake lights, then you will have to ask someone much brighter than me for a solution. Good luck!
