There is a plug and also a electrical chord on the top of my compartment. On my coach that chord if plugged in is for the block heater. In my case the Caterpillar engine has the block heater in case you are in extreme cold weather, I turn on the switch with the red light and the engine stays warm and will fire right up.

Not sure on a gasoline motor home if that is what that is for, but I have seen some gasoline engines with block heaters.
