d.That the cord is wrapped around the kingpin

You should verify the electrical (light) cord is firmly seated in its socket, secured with the safety latch if equipped, and free of cuts or fraying. A loose or damaged cord can cause the trailer lights to fail. It should also be routed so it does not drag or chafe.
