Yeah it looks like there's a plug at the top that pushes into a rubber grommet, and tags down the front side and bottom that will pull out.
Give it a firm pull at the top rear and it should unplug..
You know how the "trim clips" come out ? There's a lock pin in the center you either pull out, or push a little way in till they go loose but are still in the clip/plug(the right way), or, you push the pin all the way through and then search for it under the motor somewhere(the wrong way)..
