I wired mine into the dome lights. When the left light is on, the left floor is lit. Right light= right floor. Also when you open the door or hit the remote they get bright and dim like the rest of the interior lights. You have to solder the wires to the contacts by the switches. Tuck the wires above the headliner. Remove the drivers side A pillar, run the wires BEHIND the airbag on the pillar then under the dash. With this set up there is no need for extra fuses (there is a dome light fuse already) or switches.
