My door locks will cycle between lock and unlock at sporadic times. It doesn't matter if the keys are in it or if I'm driving it or not. I think it's the switch but could it be wiring?

Could be either. Does it have any kind of alarm or keyless entry? If so start there. Otherwise check the wiring where it passes from the cab to the door. Sometimes the wires get broken in there and short out
