Electrical help please. Lance harness to Ford truck

Thank you! I will test and go from there to be certain. You saved me some grief. I was hoping it would all just tap right from the plugs but I will have to run that battery lead after all. The ground as well. Should not present much of a problem. I spent about 90+ buck on that 5th wheel harness. I'm glad to not cut into my harness, but it really did not merit the expense. Any tips on running that 12v lead?
