Have any one modify the OEM fog lights so it can be turned on just with the parking lights?? The factory setup requires fog lights can only be turned on with low beam. I prefer to cut/splice wires near fog lights relay but need direction... Thanks.

The headlight switch supplies the BODY ECU with ground inputs which in-turn supplies the ground control signal to the FOG-LIGHT RELAY. You would have to modify the wiring at the headlight switch so that the ground is given when the parking lights and fog light switch is selected ON. You would also have to by-pass the BODY ECU so that the ground from the headlight switch is sent directly to the FOG-LIGHT RELAY. The only other thing that you would have to consider is if the headlight switch contacts can safely carry the extra current draw with the new configuration, the parking light contact will now have to carry both loads. (the reliability of the switch might be affected).
