Help! My rear seat heater is not working. When I fold down the rear seat I have connector that is not plugged into anything. It comes from the rear seat heater control module. I've tried researching parts diagrams but nothing. Pictures below... Fuses are good and switch is new

 

I will try and remember to fold my down this evening and take a look at it. I don't remember an empty plug like that but that doesn't mean much.
