Crawl under the truck with your head under the oil filter. Look up to the base of the oil filter. That is also the base of the oil cooler. The so-called block heater element screws into the oil cooler base above the oil filter. That orange electric cord you see there runs to the grill area of the truck, where you would plug it inti an extension cord.
The heater element is screwed into a water jacket. There are both oil and water jackets in the oil cooler.
Here's mine, looking up from below the oil filter. That white blob is the filter.
My Sierra Blanca in the sig pic was a great pickup for 11.5 years. I sold it a coupla years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream.
