ignition switch
The switch is located bout midway between the steering wheel and the floor board.The dimmer switch and the ignition switch are in the same bracket.Should be 4 screws holding the bracket to the top of the column.The lower half of the dash will have to be removed,to be able to acess the switch.4 bolts holding steering column up have to be removed,this allows the column to drop down.Ignition switch and dimmer can be adjusted up or down .There is a small rod in the ignition switch that will only fit one way,not sure if new switch will have one so DO NOT lose the rod.Too much adjustment and the rod will bind and not work properly,and the dimmer switch will be on hi beams all the time.
It's not that hard,shouldn't have to adjust anything.Both have molded plugs going to them so they can't be connected wrong.
