Trying to find the OEM location/installation procedures for an engine block heater. Though the ML was purchased in Denver, CO, the VIN breakdown doesn't list an engine heater being installed. Nearest dealer is 365 miles away. The posts I have searched indicate it may or may not be installed and may or may not need only the power cord installed.

Thanks in advance for any knowledge y'all may be able to pass on!!
