A system and method for post-cure application of electronics to a tire includes: a first stage assembly in which an ends of an annular antenna wire are positioned within conductive grommets in a base member; a second stage in which a plug is affixed to the base member to hold the antenna ends in place during shaping and curing of the antenna wire into a tire; and a third stage in which the plug is replaced by a tag carrier, the carrier including means for establishing and maintaining electrical contact between the antenna ends and the tag.
