It has a special connector at the visor and a bullet connector for the dash. It plugs in to the 3 terminal connector is for the glovebox light. If you did not have a lighted visor originally the truck will not be wired for it.
Well, if the colors are the same as my truck, i'm guessing the lighted visors run on the constant 12v power source circuit? So the visors would be usable even with the key off and away from the truck?
