Did it today on my 2010 STX as well. Yes, it was about $60. I think it took me literally 5 minutes. Ford makes it easy now. The cover on the dash, where the sensor would go, actually has the wiring harness attached to it. And the panel on the side of the dash, closest to the headlight switch, pulls right off with a quick tug. You can get right behind it, push the tabs down and swap out the switch.
