So I wired up some LED strips in the footwell of my JK, and thought I would share what I did since it turned out so well.
First, I bought two LED strips from the Oznium website (Google it), specifically ribbon LED flexible strips. I got two 6 inch in cool white. These come all wired and ready to go, they are only $7.99 each, and come in various lengths and colors.
First, I needed to get power to the footwells. I found it easy to get power from the rear dome light, so I unzipped the covers form the roll bars, and took apart the rear light. The wire that supplies power based on when the doors are open is the middle wire of the connector. I used a wire tap connector, and tapped into that wire, and then ran a wire through the soft padded roll cover all the way to the passenger footwell.
Next, I attached the power (red wire I ran) to the white wire of the LED, and attached the black wire from the LED to a round connector, then to one of the bolts of the door strap hook.
Next, I attached the LED strip to the side of the passanger footwell on the painted surface, near the door strap hook. To supply power to the driver side, I used another wire tap connector, and ran another wire over to the driver side, and repeated the process.
Now I have bright light in my footwells whenever the dome lights are on! I would like to do a similar mod to the back seats, and in the engine compartment.
