I popped off my a-pillar trim panel tonight to replace it with a new one and out fell a little surprise - a 2"x2" piece of white paper with a yellowish, somewhat sticky, transparent backing. In between the two layers there is a flat copper coil (9 winds)connected at each end to a small beige capacitor(?). On the paper side, the top is marked "59145"; in the middle between two horizontal lines "E39 A-S Links"; and at the bottom "4".
