So today I was going a couple places and i kept getting in the car, turning on the head lights and then turn of the fog lighs. After the 4th time I was thinking how great it would be if someone had a mod that would wire it so when you turned the lights on the fog lights came on too. A shot in the dark but hey you never know enught people on this forum some one might know something

 

haha you said "a shot in the dark" and are talking about fog lights for some reason I find that funny. Anywho that has to be 100% possible because I did it in my bimmer however I am unsure how to in the S4...sorry

 

im not sure about wiring it up to have them turn on at the same time. I odnt think that has been divised yet. However you can go independant fogs. which means u can use the fog lights without having to turn the headlights on. goto audiworld and look in the tech articles youll find it. you need to get the controler form behind the glove box and use a small piece of wire to jump two of the terminals

 

Yes..i need to do the independent one really bad...i want to run my HID's and just parking lights...thatd look sweet
