What did I just unplug?? I had a noise coming from the right front inter fender. this thing has a spin in filter in the bottom and I guess a electric motor on top. It has a hose that runs to the front off the motor and tees to two vaccum things. it also has about 5 wires. I unpluged the bigger plugand the noise is gone. What is it ? and do I need it??
