Yes to both. But I dont know on what pins (4 total) should have power or when to the actuator. Ordered a Dorman 600-901 4WD Transfer Case Shift Motor Encoder last night. Could this be the problem? If not its returnable. Thanks

"those are the number 1 cause" do you mean the actuator or the encoder?
