sure you can. trouble shooting instructions should be wth the paper work. you can test the solenoid works by supplying 12v to one of it's connectors and grounding the other. if you do one side through a toggle switch inside the car, (tape everything up), connected to one wire from the solenoid and one wire to the power or ground lead (which ever side of the solenoid you chose), you will be able to test it while driving.
