I got a 2013 Ecoboost, just put a brand new engine in but the truck was sitting for about a year when I pulled the old one out. I think I got most of everything good so far but I have a loose harness behind the driver side head, it comes off the main harness right where the driver side coil harness are. It's just one plug on it. Three pin Blue color but I can't find it's home. Can anyone help here?
