I was installing new speakers in the kick panels when this fell from underneath the dash on the passenger side. It appears to be a condenser for suppression of electrical noise - it's an RPO U69 car. If I had to guess, I would say that the copper tabs are to be inserted into the connections for the directional signal flasher which is held in place underneath the dash on the passenger side. However, I see no reference to this condenser in any of the wiring diagrams I have.
