Just finished the conversion over the weekend. the new lights and color make a huge difference.
Overall the process was pretty simple. You have to make sure you specify the current color of the bulbs you have when ordering from Deautokey. That will ensure you get the correct bulbs.
The trunk light, visor lamps and rear map light will all pull directly out of the head liner or rear trunk panel if you gently pry them out. You can then remove the wire connector to allow you to change the bulb in a more comfortable position.
Most of the bulbs are the festoon type, and when you remove the existing bulbs you may expand the existing holders making the replacement LED bulbs loose. You can gently bend the bulb holders to make the connection tighter.
The LED bulbs are polarized, so double check that the bulb illuminates before reinstalling the housing back into the headliner or trunk. If they don't illuminate, rotate the bulb 180 degrees and try again. Make sure the connection is tight as well.
The map lights near the front seats require a plastic pry tool to gently pry the light housing out of the rest of the assembly. Removing the bulb is straight forward once you have the assembly removed. Just pull straight out. These are wedge type bulbs, and are polarized as well. Double check that the bulbs illuminate and then gently pop the assemble back into the roof.
