If you want to take a economical approach you could buy a ZeroStart (Phillips & Temro) Part Number 3100040 which is a block heater kit that would give you the same element as OEM (P & T is Ford's supplier), but the cord would be a generic one that you would have to route and tie-up as you choose. Some place like NAPA should be able to get this to you for about $25.
Or the OEM approach...
