you just take off the cover from the inside in the cargo area, and you just twist the light socket out pull bulb out put new one in and then put back in twist, and put cover back in, as far as everything besides turn signals. if you do turnsignals then you need either a new flasher relay or wire in some resistors, or they will blink fast. because it uses less power and the car will think the bulbs are out when they really arnt.
