Ford does a real good job of making the cord & plug.. hard to find.. on each truck
Probably the fastest way to find yours would be: just above and to the front of the oil filter boss.. yul see where the cord connects to the heating element, on the block (replaces a freeze plug).. trace it from there.. to wherever Ford tucked it away.. [usually] it's somewhere in behind, in an area, near the passenger side grill/bumper/tow hook/headlight areas ?
