Where is this part located in the vehicle?

This will be located under the dash. We can not be more specific as they tend to move around a lot from model to model. Your dealer might have a schematic for you.

Right behind the radio, in the center of dash panel. I removed it once the radio was removed easily with the tools for removing that unit. Google the "Ford Taurus Radio removal tools" for the tools that made it really easy to get to.
