So I disconnected the wiring and took the front axle actuator out. The plunger is retracted. Then I plugged the wires back into the actuator and pushed the 4WD button, nothing happened with the actuator. I want to test it to see if the actuator is at fault, or if the problem lies with it not getting signal or power. The connector has green, black, black/white and reddish-orange leads. Which are the power blades in the connector on the module that I could connect directly to 12 volt to see it it's working? Which are the female connectors at the ends of the colored wires that go to the module that I could connect a test light to and see it power is getting to the module got power to it when the button is pushed?
