Justin, I was able to hard wire my fogs to come on when the parking lights do. Only down side is that they come on EVERY time the parking lights do. Like when you hit the keyless unlock button. No biggie though. I did a study of my truck's wiring for the fogs and parking lights and found a green wire under the dash in which I jumped to the parking lights. I am sure this can happen on the NNBS trucks--you just gotta know which wire it is...
I thought you just wanted to know who knew how to do it. But I guess I can tell you. Lets start with lows and highs on at the same time. Click here and go to post 20 http://www.ls1truck.com/forums/elect...dlights-2.html
For the fogs you will need a relay I am not going to go thru all that on how to hook it up but you use your headlamp relay in the fuse box under the hood to trigger the relay it should be pin 85 will trigger the relay once the lights are on. Thats how I am going to do mine when I have some more time and finally get a new set of fog lights one of my ballast's pooped out on me.
Also if you get a diode you can trigger the daytime running lights to come back on with the rest of the lights if you want to.
Can you wire them like the 03 and up trucks or is the wiring all different, I have no idea I have never looked at the electrical center under the hood of a NNBS so see if it is anything like this http://www.ls1truck.com/forums/elect...eadlights.html
