Yep, found the other flasher thats about above the steering column, which I'm going back to the parts store to get another one.

On the polarity, I ~thought~ I bought the ones that it doesn't matter on polarity, as I do think they make them....but I'm not an expert. I'm assuming this would only effect the sidemarker lights though.

I checked what I ordered on Amazon and they are all non-polarity versions. And dash were all dimmable.
