You should start by taking off the lower IP trim panel, remove the two fasteners that hold the heater A/C duct, and move the duct away to reach the panel dimming control module bracket. After that, loosen the three fasteners on the lamp control module bracket and take off the two electrical connectors from the module. Installation steps include connecting the two electrical connectors to the lamp control module, attaching the lamp control module bracket to the instrument panel, adjusting the heater A/C duct back into place, putting the two fasteners in, and replacing the lower IP trim panel.
