@BostonBLS and anyone else interested in a blank plug
I just removed my active air dam along with the air dam on the bottom of the bumper in order to clear my plow frame. I love the look but I wasn't happy about just taping the active air dam connector so I did some digging and I think I found a solution to make my own blank. I just ordered a part number 0535451528 which is sold as a Mercedes-Benz plug housing but from what I can tell it's the exact same connector. I found a used one on ebay for $5 so I figured I'd give it a shot. I plan to fill the connector pin holes with epoxy to seal them and then just plug it in.
I'll also through this out there-
I found these which appear to be the same connector as well but they were a bit more expensive. I also can't tell what the difference is in the MA vs MB connectors

I noticed most of these come from overseas so the shipping time may take a bit. I was lucky and found one in the US.
So I will let you all know either way when I get it, and if it does fit I'll post pictures of the outcome.
