By default, the foglight will ONLY come ON when you are in low-beam mode; DRL and high-beam will have the foglight turned OFF.



The only cons here is that the FOG light indicator is no longer true to whether the foglight is on or off.



I think by adding 1 relay & a fuse, and wiring up like how I illustrated in the diagram here should do the trick.
