Detach the radio and disconnect the antenna lead from the backside of the radio. Attach a piece of stiff wire to the end of the antenna lead, then remove any retaining clips under the instrument panel securing the antenna lead. On vehicles equipped with fixed type antennas, use a small wrench to remove the antenna mast retaining nut. Using a pair of snap ring pliers or a similar tool, remove the antenna base retaining nut. For vehicles with a power antenna, remove the antenna motor mounting screws from the inner fenderwell. Pull the antenna up and out until the wire is visible, then remove the old antenna lead from the wire and replace it with the new antenna lead. Working in the passenger compartment, pull the wire and the antenna lead rearward into the passenger compartment. The remainder of installation is the reverse of removal.
