Secondary air pumps are sometimes used to feed extra O2 to the catalyst brick for emissions. Early 3.8L GenII Tauruses used to have them. Since the Tour went from OBD-I in '95 to OBD-II in '96, they probably wired for it just in case they had to add one in a pinch (not sure where they'd stuff it with a V6). I don't know if my '99 has a space for it.
