What is this for?

Max.... take note, there is likely a switch- probably in the front panel over the passenger side seat- labeled as Block Heater or something similar. This switch applies AC power to the receptacle you just plugged that line into, thus controlling your block heater. But of course that switch will control anything plugged into that receptacle.
