Looking through the electrical diagrams trying to figure it out... I'm interested, as I have dealer-installed aftermarket front fogs, and the cars here come with rear fogs stock...

It's pretty easy in theory, just need to swap a wire so that the fog light switch is energized when the parking lights are on (which they are in both high and low beam)

So here's what you'd need to do (in theory, someone please test this first with some spare fuses handy ):

Pin 4 is the input from the low beams and/or DRL module, pin 13 is the output from the parking lights.

Essentially you want to cut the wires going into pin 4 (depending if you have DRLs, there may be two wires, I'm not so sure), then short pin 4 to pin 13.

Give it a try!

I think you would want to use pin 10 (T1) rather than 13 (B1). B1 is the non switched leg, so the fogs would always have power. T1 is the switched output from the parking light switch.
