Look on your oil filter. IF you see an orange cord, follow it to the left tow hook and that should be the plug in for the block heater. Only if you have the orange cord coming from the oil filter area, then you have the heater. From what I have read, it can be hard to find. I took a Marinco adapter and put it the plastic air dam below the bumper. I took a heavy duty extention cord and took the male end of the block heater, plugged it into the female end of the extention cord....ran about 4 feet and cut it. I took the end I cut and wired it into the input I mounted on the bumper..Look at my pictures and you will see what I did...
