Just bought an 08 super duty XLT with a V10. While I was changing the plugs I found this sensor unplugged and I have no idea where it goes. It was laying down the passenger side valve cover. But the wires long enough that it could go to the driver's side. Anybody know where it connects to?

Is your truck 2WD by chance?

If so, that's just the blanked off vacuum line that would normally be used to control the front hubs as part of the "auto" 4X4 system.

 

It is a 2wd! Thank you so much Saratoga 2011!
