I tried to search for this problem, but its hard since you can't search for "fog" or "99". I am trying to do the fog light mod (fog lights on with only parking lights). I modified the switch (which was extremely hard to do. But now I am not sure as to what wires to splice together? On my 99 there are 3 big plastic wire connectors. Any info is greatly appreciated.

Best of luck.

 

Thanks for the info. I figured everything out and now it works great. The switch isn't as smooth as it was but its not bad. It was hard to replicate the "ramp" that is in the stock switch that pushed the **** in when you turn it off. FedExPilot: I notice you have an access roll up cover on your truck? How do you like it?
