Re-wire Fog Light To The Parking Light.

[GullyBoy21]

HOW DO I MAKE THE FOG LIGHT COME ON WITH THE PARKING LIGHT?(shrug)

[910MSPRacer]

easy, tap the red wire to the battery, and the white wire to the switch wire that turns on the parking light. use a test light.

You don't say! I'll do my best to not find more than one red or white wire on the car. If someone can get me wiring diagrams I will do my best to translate and make a write up for everyone to use.

[910MSPRacer]

well, if they are aftermarket, they have a red, white, and black wire. even stock has only 2 wires, and all you would have to do is reroute the switch wire(usually white under the shitty taping job from the factory, at least mine was) to the switch wire on the parking lights. ive done it ten thousand times with other makes of cars with fogs, and it takes a matter of a couple minutes and a solder gun, with some heat shrink tubing, and i take back my harshness, as i was under the influence a little. like the commercial says, if you wouldnt say it in person, dont say in on the net. lol. sorry dude. i was just tryin to help, as you were making a point not to post a how do i in a how to area.

[JPBlackMP5]

Hey, somebody post some pix of this how to fix cuz I wanna do this to my Mazdaspeed3...and this fix seems a tad to easy per the earlier post. thanks in advance. (blah)(blah)(blah)

Well my car has been at the dealer for over a week now for them to fix the rims and dash that they scratched. When I get it back or if I get it back I will work on this and post pics and dirrections. Don't expect anything till late next week as I know the car will not be back till at the earliest monday. Till then you can figure it out yourself or wait patiently on yer bum.

i think it's a good idea to have the fog lights come on automatically; in my case [ms3gt] i'd like them to switch on w/ the hid low beams. i'm going to the mechanic wednesday to install redline mt90 transmission oil and i'm going to ask him to rewire the fogs. [i live in a condo, we're forbidden to work on cars by the nazi rules, + i don't really want to play 'learn by doing' on a brand-new car i'm not familiar w/]

i'm doing this especially because i'm also replacing the stock fog bulbs with aftermarket xenon hid-look purple [ebay, $21]. i had the same type on the crx for 2 yrs with no problems. car's now sold, don't know if they're still working, but even if the life is 2 yrs, i like the light they produce.

so i'll let you know thur or fri how it worked out. my guess is that i'm going to enjoy the 6:00 am drive to work just a bit better...the journey is fun, but not the destination...

[ElGaspo]

well, i ended up not wiring the fog lights directly to the low beams. mechanic said it was a hassle, i can do it myself by rotating the ring. only thing i'm missing out on is being able to see the fogs just by themselves, w/ no other lights on. in other words i can't see the individual lights the fogs procduce, just the mix of the hid low beams + fogs combined.

still...more than enough bright light to visualize not only in the distance, but now also can inspect every single pavement detail, undulation, pothole, crack, nook, and cranny. bright lights, big city. i'm happy w/ the ROI for $21. (drive2)

[blue-sun]

interested in this mod, if anyone knows. I always hard wire my fogs to the battery on my cars (2 MR2 turbos, my WRX, a 91 integra and my Protege MP3) as I like to drive with lights on during the day and IMHO fogs + parking lights = FTW.

Either hardwire or wire to the parking lights I'd be interested in.

I know of three methods to get independant fogs.

Method one: removes the fog relay in the engine compartment fuse box and connects it to a different spot in the fuse box. You then run a wire through the firewall and tap the wire in the steering column. Result, fogs come on whenever the switch is on, and the ignition is hot.

Method two: only works on 3's with halogen headlights as the HIDs are wired differently. Involves cutting three wires above the PJB inside the cabin, connecting two of them together, and connecting the third to a signal wire. Depending on which wire you choose to tap for the signal the fogs will either be hot anytime the ignition is hot, or whenever the parking lights are on.

Method three: removes the fog relay in the engine compartment fuse box. A single wire is run from one of the positions the relay was plugged in to another part of the fusebox. Result, the fogs come on whenever the ignition is hot and remain on for ~10 seconds after the car is turned off. The OEM fog switch has no control over the fogs.

do you have more info on any one of these 3 methods, as any will work for me. More specifically, cut wire A, tap into wire B, cap off wire C, etc?

The walkthroughs for all of them are on another forum.... let me get in touch with the creators over there and see if they will (or will let me) cross post their pictures. And just to confirm you're interested in Method 2, right?

[kickniteasy]

I'm interested in 3....seems to be a bit easier than the other two

that one is super easy but it takes away your ability to have the fogs off any time the car is running. Both 1&2 still let you control them with the switch.

which would be nice....I just can't think of a time when I wouldn't want the fogs on (I don't do any drive bys or late night stalking). Of course, as soon as I do I one of my peeps will start frontin and that special someone will stop answering my calls.

Well what if you're sitting in a parking lot waiting to pick someone up and you're just listening to tunes, or have the A/C running. However if you don't mind and you just want the fogs on at all times that the car is then here you go.

What you need:
-two male spade connectors
-~10" of wire
-inline fuse (or wire with fuse built in)

Step 1: Open Hood, take cover off fuse box.

Step 2: Remove fog relay. It's to the "left" (passenger's side) of the relay in the top right corner of the fuse box in this picture.
http://img.photobucket.com/albums/v211/chrisvidecak/Other/Cars/Mazda3/IMG_0913.jpg

Step 3: Insert spade connector on one end of the wire into this slot where the relay was plugged in.
http://img.photobucket.com/albums/v211/chrisvidecak/Other/Cars/Mazda3/IMG_0915.jpg

Step 4: Insert the spade connector on the other end of the wire into this slot at the other end of the fuse box.
http://img.photobucket.com/albums/v211/chrisvidecak/Other/Cars/Mazda3/IMG_0914.jpg

Step 5: route the wire however you'd like to get it out of the way.

This mod is totally reversible back to stock simply by removing the wire and plugging the relay back in. It will turn the fogs on whenever the ignition is on, leave them on independent of the low beams/high beams, and they'll turn off about 7 seconds after you turn the car off. This mod brought to you by Videcak from mazda 3 forums.

[kickniteasy]

much appreciated.....can't wait to do it!

Wow, thats pretty interesting. I might have to try this one out :D

that looks amazingly simple. I WILL be trying that mod tonight if we're rain free when I get home. thanks!

[ITLOWNU]

If I want to do option one which pin do I take inside to the park light switch and

which one goes to an IGN source. Pics if anyone has them. Thanks in adavance

[blue-sun]

so my jerk of a friend said that the ECU will know this has been done and my warantee would be void. I think he's being an ass and drinking too much hatorade and all, but any truth to this?

Assuming you're talking about the "method one" I talked about earlier


Method one: removes the fog relay in the engine compartment fuse box and connects it to a different spot in the fuse box. You then run a wire through the firewall and tap the wire in the steering column. Result, fogs come on whenever the switch is on, and the ignition is hot.

What you do is remove the relay for the fogs. One of the posts on the relay is connected to the same "extra" spot as is used in the little walkthrough pictured above. Two of them remain connected to the same slots in the fuse box (via extensions), and the fourth is tapped off of a wire in the steering column.

http://www.xenonexpert.com/guides/fog08.jpg http://www.xenonexpert.com/guides/fog04.jpg

Those are from M3-GT on mazda 3 forums. There's a similar walkthrough over there that does the same thing as this mod, except hides all the wiring under the fuse box. As you can see with this mod it's not as clean as either of the other two methods, but can still be returned to stock relatively easily.

It was amazingly simple and quick! I think I was in and out of the garage in under 10 mins to do this mod!

Um, no the ECU won't know you've done anything and you're friend doesn't know what he's talking about. That being said the dealer could void some of your warranty for screwing around with the electrical.

Now that you've done it how do you like it?

Yah, my service writter from the dealer I bought the car at has a yellow 03.5 MSP and is on this board. I sent him a PM with a link to this thread and he OK'ed it. LOL.

So far all is good for the mod.

[Craighjr]

Well I did this yesterday morning and strangely enough today my fog lights were on when I came home on my bike. The car was off since 5pm and the lights were off when I left on the motorcycle at 5:45. I used the pictured pin under the fog relay and then used one of the 2 switched empty fuses in the front row (speed 3). My advise be paranoid of this route as the car apparently turns that fuse box on and off at will.

[icspots]

Weird, haven't heard of that happening before. Almost makes you want to set up a camera and see if/when/how long it turns itself on.

[sku11]

It works like charm....(thumb)

[jam_asian85]

soooooooooooooooooooo ummmmmmm has anyone figured out how to do this on a GT model?

Mine did this 2 times over the last month so I took the wire out a week ago or 2 and have left it out until I have time/patience to do the other rewire job where I can control them from the switch at will.

OK I dont recommend anyone with the GT model to do this, I just went outside to talk on the phone and BAM !!! the fog lights were on, so until I figure out a solution I'm un-doing this mod.

bump...just wanted to say I just did this mod and it worked perfectly fine on my 07 ms3 GT. Put on the lamin-x yellow fogs and it looks great. It goes off a few seconds after you lock the doors. I think if you don't lock the doors, they stay on. But i am paranoid about locking my doors anyways, so no worries.

So to be honest, I followed those steps, thought it worked fine for a while, and then exact same thing as jam_asian85 happened to me. Guess it just doesn't work, undid it because I don't wanna end up being stranded with a dead battery. I thought the "independent fogs" thread was the only mod that didn't apply to OEM HIDs, but yeah...

[MM BOOST]

hmmm...how long did it take before it happened?

[MM BOOST]

bumping this...the guys who said their fogs come on with this mod (thats on page 2 I believe), I had it happen to me last night while putting my downpipe on. HOWEVER, I left the doors unlocked while we was working on the car and they just randomly turned on. So I put the key in the ignition, turned the parking lights back on, flipped them off, took the key out the ignition and then locked the doors and they went right off. I think if you don't lock your doors, they have a chance at coming on. You can hear the fuse underneath the hood while they are on and then it makes a clicking noise to turn them off. Just something I observed and might help those who had this problem. Just put the key back in, turned lights on, turned them off, pulled key out and locked thet doors and they turned right off.

Mine did the same thing last year when I did this mod, after about a month they started staying on all the time, so I undid the mod and never looked back. It would do it both at work and at home, randomly. After about a week of randomness, I undid the mod.

[dizzin9]

damn. i wanna do this so bad! come on mazda, even my 03 altima has independent fogs :(

[Bakefam828]

I used the method that makes your fogs stay on all the time. The only thing I did differently is run the wire long enough so that it comes in where my optional switch spots are. I hooked it up to a simple ON/OFF switch and now I can control the Fogs with the switch. Took an extra 5 minutes. At first I left the switch messy, but then I put it in there nicely. Will post some pics for people still pondering this mod.

You just run a wire from the + on the fog relay straight to the slot in the front of the fuse box and the lights will be hot whenever the lights are on. What he did was put a switch inline with this wire.

[Bakefam828]

I will put the pics up today give me a bout an hour. But basically just like said above, I did mod that keeps them on all the time, but instead of leaving it in the fuse box... I ran the Line Longer into inside of my car. I used the same hole from my Power wire for my system. I will take a picture of it, but I dont know if thats a stock hole. Anyways, I pulled down the plastic housing where the extra switch spots are. Not all the way, I hate unscrewing and BS, I popped out one of the slots ran the wire to there and put in a switch. Simple on off. no ground needed. When initially put the hole for the switch it was too low, but you can correct that by drilling in the right spot. This entire mod costed less than 15 bucks. Pics are coming. Sit tight. New to the M3 game, but I like to tinker. So the more I do and find the more I will post
