Complete tutorial on how to put your foglights on a switch and a relay.
Tools you will need:
Ratchet with 10mm socket and extension, wire cutter and stripper or scissors, insulation tape, screwdriver.
You will need to buy these if you don't have them:
16 gauge wires (preferably), a switch, and a relay.
http://img143.imageshack.us/img143/3350/fog01pz4.jpg
Locate the fuse box and open it. Locate the fog light relay. The closest gray box out of two.
http://img143.imageshack.us/img143/7006/fog02np9.jpg
Unscrew the fusebox, and turn it around. For convinience you can remove the little fusebox attached to it. And remove the bottom cover of the fusebox.
http://img143.imageshack.us/img143/7140/fog03jn0.jpg
In all those wires, locate the 3 wires that correspond to the foglight relay. You will need to cut the white one.
http://img143.imageshack.us/img143/2015/fog04sg6.jpg
Strip the end that goes towards the relay and tape the other one.
http://img143.imageshack.us/img143/653/fog05cl4.jpg
Use the wire you bought (have) to extend the one that goes to the fusebox. That one will go to one end of the switch.
http://img143.imageshack.us/img143/5454/fog06ox1.jpg
At this point you might want to attach your relay. You will have to drill a hole.
http://img143.imageshack.us/img143/7302/fog08tv8.jpg
Use your own screws.
http://img143.imageshack.us/img143/4453/fog09le6.jpg
Use 2 wires to ground 86 and 30 on the relay.
http://img143.imageshack.us/img143/6340/fog10ju9.jpg
I used the bolt on the fender.
http://img143.imageshack.us/img143/2171/fog11fy5.jpg
Then use a wire to lead off 87 - that will go to another end of the switch.
http://img143.imageshack.us/img143/2314/fog12gk4.jpg
Now you have two wires. The one off 87 and the white one. You will have to run them both inside the car. You can do it whichever way you want but i ran them through throttle cable hole.
Unscrew the two bolts and you freed the hole.
http://img143.imageshack.us/img143/9826/fog13hv8.jpg
Run them through. You can use a help of a friend to help you run them through - they will come out where your gas pedal ends.
http://img143.imageshack.us/img143/9792/fog14yt3.jpg
They will look like this:
http://img143.imageshack.us/img143/7941/fog15xa3.jpg
Connect them to the switch.
http://img143.imageshack.us/img143/3236/fog16rk4.jpg
Then remove the foglight switch you have.
http://img143.imageshack.us/img143/2820/fog17fw5.jpg
Insert the switch and tighten it.
http://img143.imageshack.us/img143/2739/fog20cd2.jpg
Now all we have left is to connect the 85 to the positive source. I used the radio wire that coming from the fuse. Did not cut anything, just stripped a little in the middle and plugged right in.
http://img143.imageshack.us/img143/9089/fog07lk5.jpg
So in the end - you will have something like this: 86 and 30 go to ground. 87 goes to one end of the switch, and 85 goes to radio.
http://img143.imageshack.us/img143/4094/fog18re0.jpg
Then close the bottom fuse cover
http://img143.imageshack.us/img143/5818/fog19da5.jpg
Put the fusebox back in place. Then tighten the throttle cable back in place. But DO NOT tighten it too hard, otherwise you will jam the wires and the fogs will be always on.
Then when you are done with everything - just turn the car on "on" position and check the switch if its working or not. If not - make sure you did everything correctly. If it does - leave them on and shut off the car - the fogs should turn off as well.
Here is the final result:

nice tutorial, but dude thats some shotty wiring

you need to use spade connectors, and solder and heatshrink wrap eash splice.

HIDE THAT WIRING

so, did the foglight light indicator on the dash come on too? and is there a way to figure out which one on the original switch would work so you don't have a weird one in there?

You Cannot use the factory switch because it is a momentary swith

i think it woudl be MUCH simpler and appealing to have the FACTORY relay be powered by the parking light circuit rather than the headlight circuit.

then have it be triggered by the factory switch as per usual.

that way you weird people who like to drive around with only their foglights for whatever reason can do it, but you won't have shotty wiring, or cheap looking aftermarket switches in your cabin.

and woohoo, you could have yoru brights and fogs on at the same time.

Actuall what I did was take a Blacke rocker switch and mounted it under the steering wheel, Right in the dip. It mounts almost perfect,I wrapped it a couple of times with electrical tape perfect fit

https://www.thegalantcenter.org/style_emoticons/default/laugh.gif u should of spent an extra 5 bucks for connectors and spades and just hook it up into the actual fuse...nice tutorial though.... https://www.thegalantcenter.org/style_emoticons/default/tongue.gif messy wiring annoys me...

i agree just spend the extra 3 dollars on spades and normally you dont want to ground things off to existing grounds....obviouslly this worked but i would switch it anyway and take the advice for future installs

Would you please let me know what I should do in order the factory fogs relay be powered by parking light circuit rather than headlight circuit?

that hasn't been figured out yet...it seems that the factory button trigger the ECU to turn on the fogs, not another relay.

I know there is a way to do this somewhere. ive seen it done a long time ago. ill do some searching and see what i come up with.


edit: ok i found it but the link is dead. here (https://www.thegalantcenter.org/index.php?showtopic=3925&hl=)is the original post. i contacted djscript to see if he would repost it up.

if the fogs are powered by the parking light would it have enough juice to spark up HIDs?

I want to do an independent fog mod and eventually throw HID lights in there

did this upgrade a while back but w/out the relay. i tend to forget to turn em off sumtimes but luckily i dont have to worry bout draining the battery since i got an optima yellow top 8) i noticed you placed the toggle switch where the stock switch was but i placed mine in the tray slot below the a/c controls. easy to get to and it looks clean. bought an led switch but decided to go w/ the toggle switch since the led was bright as F**k and the placement wouldve blinded my rear passengers :shock:

I have no electrical knowledge but couldn't you just tap into the running lights with the fog wires rather than doing all of that? Like if you only wanted the corners and the foglights on you could do that by running the fog wires to the corner wires correct?

pinoyesv6
10-10-2007, 11:26 AM
technically you can do that but you wont be getting the full potential of the lights by just tapping power from the parking lights.

great tutorial, helped a lot!!! i wired the positive in to my parking lights instead of the radio so the fogs cant be on unless the parking lights are

thanks again!

you don't use the parking light circuit to power the fogs.....

you use the parkinglight circuit to trigger the FACTORY foglight relay.

it literally take about 3 inches of wire.

and thats it.

please do do your wiring without connectors or a relay pigtail if those exposed power wire touch the body or something you could have some serious problems

get one of these you can find them at pretty much any auto parts store or home depot/lowes)

Hey guys, just did this tutorial without a seperate relay, and they were working fine for two days, but now the lights dont come on anymore. checked the fuses and they are good. i have a led switch to let me know when they are on, that light turns on when i switch on, i hear a click when i turn the switch off and on from the actual foglight relay. i checked the ground and thats also good. has this happened to anyone? i wanna know first if it mit me the actual bulbs, cause its a bitch to get to them since the car is lowered and its the VRG fogs. so help me out.
