Yes. You can then turn it on without the headlights. Also another mod is to make them not go off, when you are using the HighBeams.

I agree...and the title edited to include "2006" too .

After all these months, the mod is working perfectly with no issues.

One thing that I noticed about the indicator on the fog light switch. Although normally it doesn't turn on when the headlights aren't turned on, if the headlight stalk is pushed for high beams, the indicator light will illuminate even when the headlight switch is off.

lol ya! include 2006 in that title..!

Maybe the indicator light within the fog light switch draws power from another leg in the relay (also feeding from the v12 you tapped into)..?

Glad to hear it's been working for months without issues.. can't wait to try it.

Just curious... is having this setup bright enough for driving at night with thick fog? I'm worrying because my 06 factory foglights are quite small and don't seem to put out a lot of light.

I have the same fog lights as you. They only illuminate the very front of your bumper. I've driven in some really, really, pea-soup fog in the past. In that kind of fog you actually don't want to use the low beams because the reflect too much glare. With the ability to turn on the fogs by themselves without the low-beams, I'm able to drive with better visibility in more situations without worrying about glare.

Of course, with fog that thick you would be driving very slowly anyway so the fog lights do provide enough light.

Under normal visibility conditions (and light fog), the fog lights by themselves are not bright enough to drive at night because they only light up the front of your bumper (like they are supposed to do). They are bright enough during the day to act as DRLs though.

I made this picture to hopefully explain a few things about the foglight mod.




What the original poster posted basically is the relay half of the positive side of the mod (red text). Doing this only does allow the fogs to come on without having headlights or parking lights on, but the switch indicator does not indicate the same. You should do the same to the switch side of the red/green wire.

Foglights going off when you flash/turnon high beams is caused by the ground side (blue text). Ground the yellow/blue wire and you will have fogs stay on even if you flash/turnon high beams.

The wiring must be different on the 2006's because with this mod the fogs stay on all the time even when you flash/turnon high beams. No extra wiring or cutting is necessary.

Perhaps it's because the laws are different in canada, in the states there is a maximum of 4 lights on at the same time on the front portion of the cars, so foglight cutout with highbeams on is standard on factory installed fogs. In other words, you may not have the ground side of the fog relay wired to the light stalk. But I checked while rewiring my own car (2006 WRX) and it's definently there.

There has been a similar mod on ScoobyMods for a few years now. I don't know how this mod is different, but with the ScoobyMods mod, whenever I run my fog lights alone, one of the bulbs eventually burns out in about a week or three. Then the other. So it might be getting a surge of energy when the power is turned off (when turning off the car) that is dissipated more when low and fogs are on together.

So I did the ScoobyMods foglight mod, but I almost never run with only my fogs on now because I don't want to have to replace the damn bulbs. Anyone else with similar experiences?

This mod is different than the ScoobyMods one because it doesn't burn out your bulbs in a week or three. I've had this mod since early this year and have had ZERO problems.

So... will my fog light switch still function? if I do this mod?

Yes. You'll be able to use the switch to turn the fogs on anytime you want--not only when the headlights are on.

Oh ok.. Cool! I was under the impression that the fog lights came on whenever 12 volts was put to the bent side of the relay, but having the stocker oem switch lets you turn them on or off... good deal. I'm gonna go do this mod.

I figured this might be a useful visual aid for any who have problems understanding the wiring diagram.

Zalthras-

So let me see if I got this all straight.

The car: 2006 WRX Sedan or Wagon US spec

The Goal: Be able to turn the fog lights on with the factory fog light switch when the head light selector switch is in any of the following positions: Parking lights only, Low Beam, High Beam, and Headlight flasher aka flash to pass. The parking light switch on the top of the steering column will not enable the fog lights after the mod, just as it does not enable the fog lights in the stock configuration. The stock factory fog light switch will still illuminate and dim with the brightness control, and the on/off indicator portion of the fog light switch will still correctly indicate the status of the fog lights as on or off correctly, after the mod the same as it did before the mod.

The Method:

Remove the Fog Light Relay and bend the #23 pin so as to be accessible when the relay is plugged in, as shown in the above photos. (This also effectively cuts the Red/Green wire at the fog light relay)
1.Attach 16 gauge wire to bent relay pin and connect to the Black and Red wire labeled FB #10 in the wiring diagram above
2.Cut the Red/Green wire where it comes out of the Fog Light Switch and also connect it to the F Black/Red wire.
3.Cut Yellow/Blue wire coming out of the fog light switch and connect to ground (Black wire).

(Note: It is my understanding that the 2006 WRX uses a "variable ground" to change the brightness of the dash lights. Be sure that you DO NOT use this "variable ground" to ground the Yellow/Blue wire. Test the resistance of the ground you choose with a multi-meter it should be somewhere near 0 ohms) and does not change when you adjust the brightness of your dash lights)

A question:
Based on the wiring diagram you posted, which I assume is for the US Spec 2006 WRX, it looks like you suggest taking the Yellow/Blue wire to ground BEFORE the Diode. Now, please correct me if I'm wrong, my understanding of a Diode is that it is a directionally limiting device, i.e. electricity only flows one way through the diode and is thus a circuit protector of sorts preventing the flow of electricity in the wrong direction. So based on that, is there any reason why you could not choose to ground the wire labeled YG (Yellow/Green I assume), instead of grounding the Yellow/Blue wire?



If this is all correct, I hope it solves some confusion.

Thanks

Couldn't have said it more thoroughly myself.

I didn't bend the relay pin on mine, instead I cut and rewired the wires behind the relay housing. But it should work the same.

Yes, the diode prevents reverse current flow leading to current noise and protects circuitry, but I didn't see it necessary with the rewire since the only switching that will be done is by the foglight switch and relay (nothing that needs protecting). Also the only device that needed protecting against and would have possibly introduced enough noise to cause the relay to toggle in someway other than expected has been removed from the flow. (This is the headlight stalk via. the user flashing the highbeams causing the fogs to cutout multiple times and bouncing current backwards at that point introducing noise into the ground as current flows from negative to positive.)

I hope all my run-on sentences made some sense.... in short, I felt that it was an unnecessary 0.7v drop device in the circuit once you make the wiring changes I showed in the picture. You can by all means leave it in if you want.

Soldiered it on. I also shaved the clips on the side to make it easier to remove next time.



Got the add a fuse at Auto Zone for 7 bucks.

End Results:




However, I didn't cut any wires behind the foglight switch. I just connected it the way I have in the picture. is it bad how I have it hooked up? It seems to work just fine, but I don't want to break anything.

That's exactly how I did mine and I haven't had any problems at all.

The only thing I notice is the fog light switch indicator light will dim down a little when I turn on the brights.

I tried this.. I couldn't get the relay back into the relay holder with the leg bent !! how did all of you guys manage to get it back into the holder?

Only idea I had was to 'trim' the relay box, but I didn't want to do that..

any ideas??
