Recently my mazda 3 2013 skyactiv sedan started making weird noises in the front passenger side. I think it has something to do with the steering, because the sounds get louder when I turn. It's kind of a humming noise. And I noticed it's quieter as I go over 50km/h probably because of the road noise covering it. I also noticed a plug that is unplugged in the engine bay I have included a picture can anyone tell me what it is? I took it from this angle in http://postimg.org/image/8mrvjcxch/ and then I took a picture not zoomed in http://postimg.org/image/595ul1v9f/ and then zoomed in http://postimg.org/image/fjexpbnin/. I also included a video of the sound, the sound is more noticeable when I turn the wheel so I turned it in the video. https://www.youtube.com/watch?v=T7p4GPexcdI&feature=youtu.be
