I am adding driving lights to the front of my 2013,I want to set it up so I can hit the fog light button and have my driving lights work the same as the original fogs they are replacing, but in reverse, on with high off with low, I also want the light on the dash to come on when the driving lights are on, does anyone know if first I can program the bcm to work in reverse like that, and if I have to use relays, what wire do I tap into to make the fog indicator on the dash light up
