I received this part unattached when I bought this 2007 M45. I haven't been able to locate exactly where it fits. The part number shows it on the driver's side. I've looked on the passenger side and didn't see another to match so I'm not sure where it really goes. The exploded parts view, #11, shows it somewhere under the fender well, in a vertical position. Can anybody help me here? Maybe post a pic of it installed on the car so I can see where it's supposed to be? Thanks!!
