With the system complete, we needed to hook up some power and see if it works, and check and see if the wipers will park in the right location. PWD provides this cool little way to check how the wipers will perform without having wipers. Use some zip-ties as shown to act as wiper arms. We set the zip ties and hit the switch, and without missing a beat away they went. Things worked nice and smooth and the motor was very quiet, even though it's in the passenger compartment. Not too bad for a system that only cost $429.95.
