OEM fog lights to turn on with parking lights

[subiestyle]

I've got the oem fog lights on my scion frs.

They only turn on when the regular headlights are on and the button is pressed.

Is there a way to mod them to also turn on with my parking lights?

I've run a new relay harness to my lights and I've spliced into the stock switch output to trigger the relay. I can now turn the fogs on whenever the parking lights are on and they also remain on when the high beams are on. The dash indicator still works, but only when the headlights are on.

is there a wire from the switch where it can be connected to the parking light instead of the low beam.. on that note, some state its illegal to have the Fog on with the Hi.. In my BMW you can turn the fog with the parking lights and shuts off when you flick the Hi on..

what is this dash indicator? You mean you get an indicator to let you know the fog lights are on?

and do your fog lights turn on with your daytime running lights?

The switch actually provides power when the parking lights are on, but the stock fogs don't come on until the headlights are on due to the fact that they're computer controlled. The power remains on when the high beams are on, but again, the computer turns the fogs off since the computer controls the output to the stock relay (hence why I'm bypassing it).

I specifically want the fogs to stay on when the high beams are on since I'm putting HID projectors in the fog location. I don't want to stress the ballasts/bulbs by turning the fogs on and off each time I light up my brights.

I've already removed my DRL resistor, so thankfully no DRL for me.

Ok, I remember my Smart Car, I had the "computer" flashed where the program it to go on with the parking light.. Si I wonder if that could be done with the frs

Go find out, I'd love to know as well.
