Follow the wiring, see where it goes. If it is a block heater, you use it in extremely cold regions, so hopefully your engine fluids won't freeze. You just use it overnight. Different type heaters may work better for some vehicle systems, but, basically used to ward off the cold.

I realize this is an old post. In the future, hope you don't have any vehicle issues, but, if you do, keep the site in mind. They are always working to improve the site and it's free.

Have a good day.
