I picked up a new to me 13 Sahara JKU last year. Things I have learned, plan ahead for electrical, and probably just about anything else you want to do.
The JKU came with aftermarket round LED's someone had drilled in the bumper. Took 3 days to find the switch, it was taped to a wiring harness under the dash. It also has 2 pillar mounted lights. Finding the switch for it was also like the hunt for Red October, it was taped up under the passenger side dash. I decided to replace them with with LED light bars, and after seeing the wiring mess bought an sPOD to clean it all up, well worth the investment, and really cleaned up the previous owner's mishmash of wiring. As an added bonus I picked up the sPOD from the manufacturer and met the owners, really nice folks.
