I did this last night. When I got under there and found where it is, my immediate thought was WTF!
Anyways, I very calmly and patiently worked my hand in there. It took a few mins but I was able to do it entirely by feel. When your hand is in there you won't be able to see anything. The good news I guess is that it does connect very easily once you get it in there. Patience is definitely a virtue for this though. If you have very large hands you probably won't be able to do it.
