Take the dash apart first or just go ahead and buy the bulb socket pigtail for the dash light bulb as a large percentage of the time the holder will be disenergrating upon removal as it is made of a poor grade of plastic , it is probally kinda meltedThere is a light bulb that can be accessed easily when you remove the whole panel from the cab....usually 3 screws. Right there on the back of the panel is the bulb holder.
