An apparatus for securing wire harness terminal connectors to the underside of an electrical junction block in a blind assembly operation. The apparatus includes a flotation bracket with chambers for receiving the connectors in a mechanical snap-fit in which the connectors are free to float up and down over a limited range within their respective chambers.
