Walmart sells a complete wiring harness with remote control that you can use to hookup factory fogs or extra fogs(lights). Doing it this way eliminates the need to go to dealer and have car computer reprogrammed so fog switch will work($$). Hooks up in 15 minutes and is fantastic. If hooking up factory fogs just get proper bulbs, insert into factory holder, plug wire from lightbulb into harness, ground the remote controller module and hookup power wire to fuse box for power. You are done.
