No, I'm trying to figure out what the round plastic part is to the left of the wires in the photo. It's empty but it looks like something should be in it. That's why I'm leaning toward a filter.Isn’t that a cable in the picture behind loomed harness to the right of item in question? If so follow that under your RC screen where ill bet your find it plugged into the V2V port. Is it a Northstar premium? Im still thinking it was added by the selling dealer.
