CX-9 Block Heater Plug Location

I just bought a 2008 CX-9 in Chicago that was originally from New York. If this vehicle had a block heater plug where would it be located in the engine compartment? I have done a quick search and haven't been able to find anything or been able to find anything in the manual. Thanks in advance for your help.

Not a factory option on this car. Have not heard of it being an aftermarket either...
