I just got fog lights installed on my 2007 NAH by my personal mechanic. The dealer installed the actual lights for $300 but would not install the wiring. I had to remove the lights to pass inspection because the lights were not working when I needed to get it inspected (end of the month). So my mechanic removed the lights and put back the plastic covers. My mechanic re-installed the fog lights and wired the lights through the front battery positive conection installed a high current relay, put in a special fuse and used marine waterproof connectors to avoid any water. He put a special lighted switch on the fuse door to the lower left of the steering wheel. I was charged $400 in parts and labor. It took him 5 hours to complete the job. But they work!!!!
