Hi there I'm just wondering if anyone found out the part number of the adapter that Jason had mentioned? My wife's Fiesta (Titanium 2009) has the same issue re: buzzing. The buzzing stops when I remove the sensor from it's dash mounting, so I know that's the issue. I'm tempted to just leave it disconnected from the dash and cable-tie it to the other wires, like Steven's solution above. But I'm worried this might stop the climate control from working properly i.e. it won't measure the internal temperature correctly. Many thanks! Rob.
