Just get one of these:

Had the yellow brown wire senerio on a '02 EX with auto headllight option . Worked but one thing I didn't see anyone make a note of is that the option to turn off the fogs at the switch when the headlights are on in either position is done away with. Fog lights are now on any time the low or high beams are on and cannot be turned off unless headlights are turned off.

 

Time to bring this thread back to life !!! I've read a few threads and none seam to relate to my particular set up. I have a 2000 f350 xlt with no factory headlights. I upgraded to a gos headlight harness for brighter lights and it worked great. Since I still had the other vacant headlight connector, I decided to add factory fog light with the purchase of an additional harness and it works great. Now, problem I'm running into is no fog light when high beam lever pushed forward (lever pushed away and stays)so both high and low stay on. Fogs do work with when flashing (lever pulled backwards or to steering wheel or you). Whats the wiring difference in the two directions wiring wise? Thanks

 

The FOG LIGHTS are NOT supposed to be illuminated with the high beams. EVER.

The reason yours work with the flash-to-pass is because the low beams are still technically on.

 

Thanks for the reply. I understand them staying on with the low beams, as thats what they are connected to through the harness. so are the lows suppose to turn off when you flip the lever forward? Because for some reason mine dont.

 

Yes. The low beam should shut off when the high beam position (forward) is selected.

 

Is it the way the upgraded harness is wired that the lows dont turn off in forward position? because my excursion with the same harness does the same thing. Or is the only harness working properly the one connected to the fogs?!! LOL, just my luck.

 

Didn't this get hashed out in another thread? Am still waiting to see the statutes that make this illegal. Just say-in. If running high beams and fogs at the same time is not compliant, somebody should call Daimler-Benz and tell them that their all their cars are running illegally by allowing the high beams *and* fogs to illuminate simultaneously

Still remain willing to eat crow on this one, but am simply coming up short where running the high's and fogs goes against any laws / rules / regulations with the headlamp assembly that our SuperDuty trucks use. Naturally, doing so where it will blind oncoming traffic is illegal in many (if not all) places, but we can do that without the fogs and an OE configuration.

Now, change the scenario a bit to a headlight assembly that uses *separate* high and low beam lenses, and Yes, running fogs at the same time as the high's will likely not comply as that creates 6 forward facing lights at the same time.

 

I would think that it wouldn't pertain to our trucks since our high and low are in the same housing and on the same bulb. Unless an officer was to physically check to see if you have your highs and lows wired together( highly unlikely), you technically are only running four lights. I think the law states 6 lights, as in 6 individual lights.
