The removal of the original dash will be covered through the next few posts. Follow each step and you will not run into any issues.
First and foremost... begin my disconnecting the battery. If you fail to do this, you will definitely return to your truck with a dead battery, not to mention the opportunity of shorting out the system while working on the dash rebuild.
You first need to remove the light switch from the top left on the dash. In order remove the switch you will need to reach (up) behind the dash and locate a small push switch located on the top of the light switch itself. Before pressing the switch down, pull on the light knob as though you were turning on the headlights, then push down on the trigger behind the dash, and continue pulling the light knob which should remove completely from the dash.
Next move over to the wiper switch. Turn the switch as though you were turning the wipers on high. Once there, peer behind the knob and you will see a small standard screwdriver slot; take a small standard screwdriver, turn to loosen the retaining screw (do not remove), and pull the knob off once it is loose.
