Which 6 pin plug are you saying isn't connected to anything? If on the trailer, no problem. If on the MH, then perhaps that wire has become disconnected and is shorting out. If the wire is there, I'd disconnect it and tape the end up to prevent it shorting. I'm surprised you haven't blown a fuse, each wire going into that plug should be fused somewhere.
