Engine block heater electrical plug

There is a thin spring type washer (which can be turned to release) on the cord that is secured on the threads of the block heater. (It can be seen from underneath.)
Then just pull the plug off the heater.

Location of block heater
Admittedly not car smart. Googled location of block heater. Located pictures. Still dont quite understand where it is. Is it on the side of the block? Assumably we have to remove the air filter thingy... Sorry. Just trying to find to attach the cord
