I finished installing the ARB back-up light kit. It is a fairly complete kit. It comes with all wiring, switch, relay, connectors and light. The only thing I added was a Garvin universal mount bracket to mount it to the rack I have over the spare tire. It's spliced into the backup light wiring. With the 3-way switch you can leave it to come on when you put the Jeep in reverse, disable it, or turn it on manually.
