Does anyone know if the electrical system is the same for a 12+ F150 and Expedition? Particularly with the starting system? I have been virtually given a remote start system for a 2013 F150 it is only a couple digits off for the 12 Expedition remote start bi-directional oem part numbers. Can I make it work or should I sell it and get the right one. The remote start is brand new in the box and plastic bags still factory sealed.
