I just installed a fog lights kit that bought from amazon ( which said OEM but sadly it was not so Im not happy) but anyhow. I installed it and popped in the switch. It works except the LED on the switch supposed to light up as well as the fog light symbol but it did not. I think it might have something to do with the wire harness. I do not how to trouble shoot for it. I tried to "homemade" a extra Yellow wire and stick it in one of the empty slot of the plug. But did not work. I post some picture here. If anyone know about electrical, please help. thanks.
