Just purchased a 2015 EcoDiesel.  I do not see a heater cord. Having had a previous super duty 6.0 ford that had to be plugged in when it got cold out.  Does this engine require to be plugged in.  I live in Minnesota, the truck was originally purchased in Minnesota as well.  The dealer said to look under the plastic cowling by the passenger side headlight for a cord (not there). Also to look for a orange or red plug under the manifold at passenger side wheel well. I could not see anything  not sure I'm looking in the right place.  
Thanks,
Andy
