Unless you live somewhere that gets -25 or colder its really not needed.A good battery with a lot of cold cranking amps is all you will need.

i plug in at 5f or colder.

more heat quicker is better for you, and fuel economy and the oil pressure is better

drivers side of the block, 1st freeze plug from the front

the electrical cord is zip tied to the trans cooler hose

i have the plug hanging out the front under the plastic headlight shroud drivers side, cord laying on front bumper...so i dont have to open the hood all the time
