One probably goes to the frame. The other negative and the positive cable goes to your distribution fuse panel and converter.
In today's RVs the old frame ground is only for safety. All devices have a ground and positive supply ran to them. No longer using the frame for a return line. The ground return lines are all connected together behind the distribution panel.
