So I got a 20" light bar to replace the fog lights on my 06 F350. I watched a video showing wiring through the factory for wiring using a pigtail off the factory connector. Now I know there's a difference in power draw between a good rigid bar vs what I got is a cheap Chinese model from a local shop. Anyways, I tried this method and no luck. There's power going to the factory connectors and the light does work off the battery. Can I still wire them through the factory wiring if I go through a relay?
