Perhaps those of you who've had more experience with these new-fangled trucks can lend me a hand here. Try as I might I cannot locate my engine block heater. I had the VIN researched and my '99 F150 4.6L is supposed to have had it installed as a factory option. Even a hint in the right direction would be greatly appreciated.

Thanks in advance

 

Take a look under the truck at the lower part of the engine block. There should be a block heater installed in one of the frost plug holes on the driver's side. The cord should run from there along the frame to in behind the bumper.
