Is there a way to re-wire the fog lights on a 2006 Pilot so that they'll come on without having to to turn your headlights? If there is a way to re-wire please share :rolleyes:

Hmmm... I'll bet it's a lot different in the '06, since they come from the factory with fogs. Tread carefully on that one and do your homework before you dive into this blindly.

I believe it might be illegal to drive with just the fog lights on in some areas of the U.S. so they just made it universal for all automobiles. Most cars fog lights should turn off when the high-beams are engaged to avoid blinding the other drivers.

If anyone has any wiring diagram of the 06 Pilot, i'll figure it out and make a DYI page with pictures. I did this to my Maxima, the process is rather easy. We need to know what the relay is for the Fogs and then change the Variable power supply that is currently being fed by the head light switch and change it to the source of your choice. In my example here the new source is the Parking lights. I do mine with a constant power supply. So they can be on totally independent of all other lights. As far as it's illegality, other car manufactures call this idea Day time running lights and Insurance companies even offer a discount for it. :D

You could probably just run a jumper from the positive on your parking lights to the positive on the fog lights, no?

No, in a simple world that would work... If you would do that you would probably blow a fuse. This is why they are actually switched at the relays "Low voltage switch". You would have to have the positive on your parking lights trigger the switch. This is assuming they have a positive trigger switch, I've seen some that are constant positives and the negative is the switched variable.

OK. This is how I did it on my old Ford Probe years ago and never had a problem - just assumed this is how most people do it since I see a lot of vehicles with oem-looking fog lights on without the headlights.

Correct, your way will work... However, IF some of those people then blew a fuse and said OK, this is a cheap fix.. Replace the fuse with a higher amperage one and then it no longer get's blown... Your done.. It will work and you have achieved your goal...

But then Let's then say there is an actual problem with the original circuit and because of the more tolerant fuse it doesn't blow and causes a spark and starts a flame and melts your car... All that because a fuse was changed.. Yes, it's far fetched but yet possible.!!!

Relay's allow you to control a high current / voltage item at low voltage / currents...

Bottom line here, YES all they need is a different power to light up, so you are right...

However, My way allows me to still have use of the in cabin switch as where if you were to simply put the parking lights power to the fogs you would loose this function and have NO way to shut them off other than turning off the parking lights..

I did this mod on our 98 Maxima.

I found the fog light relay under the hood. I pulled the relay and probed the socket with a DVM. I found one pin that had 12V only when the low beams were on.

Right next to the fog relay was the rear window defog relay. The same pin had 12V only when the vehicle was running.

So, I simply clipped the low beam 12V line, and connected the fog relay to the 12V line when the engine was running.

Then, the fog lights could be turned on whenever I wanted, as long as the engine was running.

I'll probably do the same thing to this car.
