I love a good mystery. Found this under the passenger seat when I pulled out the jack package to lower the spare tire for cleaning. About 40mm square and 15mm high, looks like maybe a plug for a square hole or tube, has textured surface like part of dash or trim on one side and snap-in tabs on the other side. Numbers 30008 CAV.2 USA 24607 TPO and the MoPar logo molded in the backside. Anyone know where this goes?
