Mercury F29Z-11572-D Ignition Switch

The ignition switch can be removed by disconnecting the cable from the negative battery terminal. The covers of the steering column and knee bolster should be removed. For old models, the column is lowered after removing the retention nuts. On new models, remove the metal reinforcement panel. Remove the switch screws and unplug its electrical connector. Disengage the actuator pin from the switch. To install, ensure the new switch is in the "Run" position. Place it on the actuator pin and install retaining screws. With that done connect the electrical connector then install the upper steering column cover. Lastly, raise the column and install nuts for retaining purposes. Install lower column covers then insulator panel.
