Is there any way to splice the wires for the fog lights onto the wires for the headlights so the fogs automatically turn on when the headlights do? Im the son of a plumber so me and electronics dont mix well, so finding out on my own isnt an option. Just wondering if an electronics buff could give me some help.

 

errr since ur not good with electronics ill try but it prob wont do any good.


a relay takes a signal and in turn switches a switch to let power to an accessory.

all u need to do is make a relay harness that when it gets the signal that ur DRLs or w/e u want is on that ur fogs will turn on.

this is the safe and proper way to do it. with a fuse inline after the relay.

its actually pretty simple if u kno wht ur doing

 

What you suggest would mean putting both on the same circuit, which would overload it. You need a remote switching unit. What that means is when power is on to the headlights, it sends a signal to an electronic switch which is connected in parallel to the fog light button on your dash. The unit would essentially do the same thing your finger does by pushing the button.

 

Dont be lazy and push the button. lol

 

Well I would probably ask a friend to help.. but if it takes too much effort than its worth, I wouldnt do it. Its not that I mind pushing the button, I just figured if there was a semi-simple way to get the lights to turn on automatically, why not do it?

 

I want to know why Chevy didn't do it......

 

 

its a habbit after you do it a few times anyway

 

Because it's not 50 state legal. That's why fog lights are always goofy - some places you can't run fogs without your headlights on, other places you can't run fogs unless conditions permit, I don't know of anyplace that it's legal to drive with your fogs on when your high beams are on (which is why our cars shut them off when the highs are on).

If you think a button is bad, my mom's Sebring you have to have the headlight knob turned on on the steering column, then you have to grab the end of the knob and pull it out to enable the fogs to come on.

 

yes on nissans and some other cars it is part of the headlight switch and is almost like wipers, once you engage it, it stays in place and they come on automatically everytime the car starts.

 

as long as they both use relays to turn on, you could splice the fogs into the headlights as long as they both use a 5volt or both use a 12 volt reference to turn on.

 

you know i wondered the same thing and i know that the drl's are on constant power with a open circuit thats constantly open unless the parking brake is applied which closes that circuit.

so feasibly if i can find that circuit i can either cut it and run it to my fogs instead but what i dont know is if that wire is run in series and all my friggin lights will go off but if its run to the e brake it cant be in series it has to be separate wires

so im guess all i need to do is find my multi-meter and what ever light has no power with the e-brake engaged is the DRL's and the circuit should open with the e-brake disengaged.

if it sounds like im rambeling its cus i am but someone tell me if that sounds about right.

 

Yea, my father's 2006 Jeep Liberty Limited is the same way, except he can roll with the fogs & parking lights on. And he does!

Ford has it so, if you pull out on the switch, than the fogs are engaged until you push the switch back in. -- Depending on what setting the switch is on (auto, off, parking lights, headlights)....

 

yeah it really is

 

thanks for the input.. Im probably gonna talk to my friend, he went to school for this kinda thing so Im sure he can help me out if I run into any issues.

Its like I said, I dont really mind pushing the button, its just if theres a way to do it automatically, why not do it?

 

i was wondering if its possible to just change out the button to one that stays locked on and locked off, if that makes sense. you know one of those buttons that makes a click when pushed haha

 

What if you put a bigger fuse? I'm just taking a guess I'm clueless when it comes to electronics. But I'd like to know this my self. It would be great if someone made a how-to as I do better by seeing how it's done, rather reading how. I just comprehend better that way.

My dad's lexus has that.

 

The purpose of circuit protection (in this case a fuse) is to protect the wiring, not the actual thing (in this case the lights). So unless you plan on putting in higher gauge wiring throughout the car, no, you can not just put in a bigger fuse.

 

Oh. Hmm ok. Well then if someone can make a how to on making the fogs automatically turn on with the DRL's, it would be greatly appreciated.

 

anyone? anyone at all??

 

thats not possible...hen the fog are turned on the DRL's circuit is closed and they go off.

 

He won't be responding.

 

oh i wasnt trying to be a dick i as just saying

 

yes...this is the way i have mine setup..

your wires will not burn and your fuse will not burn if you just splice them in...ive had mine this way for over a year

 

I wouldnt mind doing this, Just dont wanna splice up the factory wiring
