Thanks for this DIY. There were some times during the install in which I kept switching the polarity with no success b/c I didn't know at the time that the accessory power shuts off after some time. The front Dome lights were a major PITA. I did it the most unconventional way. That was by sliding my hands through the top and twisting the bulbs out through the top since I had no idea as to how the housing was lowered. Anyways, I am glad everything works.
