I ordered a kit from this website, but after seeing how easy it is, I figured I would do a write up for those wanting to do this. The kit is nice, everything is included, but this could probably be done with $10 or less in materials from a local auto parts store.

Link to what I bought:

http://www.mrtaillight.com/product_info.php?products_id=642&osCsid=fa9cf925e780fbb69b7016b8af1560b3

What's included in the kit that you would need:

(1) standard relay
(2) wire taps (or t-taps)
(2) connectors into the t-taps (not sure what they're called)
(4) pieces of 16 gauge (or whatever you want to use)
(1) inline fuse
a few zip ties

Start off with the relay, I mounted it to the same bolt that holds the back of the headlight in place. That done, I ran the ground wire to the small bolt that holds the bumper to the fender. You'll only need about 6" or so from the relay to that bolt. I ran power to the battery with an inline fuse. Run a wire from the relay to the white wire with green stripe that goes into the high beam housing on the back of the headlight. I used a t-tap here. Then from the relay, drop a wire down inside the fender to the driver's side fog light bulb. Throw a t-tap on the driver's side positive to the fog light bulb (I tapped it to the connector that the bulb plugs into). I used a few zip ties to keep things neat.

That's all there is to it. As far as functionality, high beam works with the fogs as well as lows. Even if the fogs are off, when you click the high beams, the fogs kick on as well as high beams. The parking lights and headlights still function as normal.

I don't have any pictures as it was after dark when I finished tonight, but it's really pretty straight forward. The biggest hurdle was just knowing which factory wires to tap into.

Thanks.. I've been wanting to do this mod.... I was going to order the kit from the link you posted just to be sure I got all the parts I'd need and since the kit is under $15....but the postage was almost $20... so I'll try to find the parts locally and follow your directions..:smiley_thumbs_up:

Good how to, (reps for that) you got pics to go with it? Mods we might want to move this to the knowledge section! Thanks again

Sweet write-up - reps for ya. I wanted to do this, but ended up adding some aux lights behind my grill that aren't tied into any of the factory lights. I got nervous about tying into any factory wires (wasn't sure my dealer would overlook it with any potential warranty issues).

OK, I'll show my ignorance:
What exactly is a "standard relay"? I'm sure it's 12 volts but is there a certain amperage or part number I should ask for?

Thanks guys! The good thing about the kit I'll say is everything is already tied in nice and cleanly to the relay and enclosed in that black wire loom so it remains hidden. Now...is that worth $30...no, seeing as how you can buy that stuff for like $5. Just saying.

By standard relay, I just meant nothing fancy. I did forget to mention, you'll need the connector that goes into the t-tap from the relay. Not sure what those are called, but you'll need 2 of them (one for each t-tap). Going to edit the first post to reflect this.

Pics, well of course they always show proof! I promise the other side works too...otherwise I wouldn't have taken the time to do a write-up. :D

Nice write up man it would of helped a little when I bought the oem replacement which only gives picture directions. The only problem I have with fog lights on with high beams is that I have heard from a few local police officers that its illegal (not that you will be running your high beams + fogs around a cop ) just something to keep in mind. Another way to be able to have fogs on whenever is to run it to the + on the running lights. I did not so this and instead followed the stupid directions and my fog lights only come on when I have my low beams on. I have installed fogs lights many times but this time I clearly wasn't thinking, but after all the wiring and removing the headlights I decided to leave it. Maybe I'll fix it this summer. Did you also have to drill a hole in the dash for the fog light switch or did you mount it under the dash?

Not sure about other states but it will not pass inspection in VA unless they cut off when high-beams are on.

I found the kits on ebay for $25.. It might have been cheaper to buy the parts locally, but at least now I'll have everything I need at one time.
Thanks again :smileup:

A switch? This is tied in with the factory wiring. When I click the stick for high beams, the relay kicks in.

I hadn't thought about that. Simple fix though, all you have to do is unhook the relay from the battery and everything is as it was before.

Alright my bad it just sounded close to the OEM kit that I installed. And I know that there are two different styles of OEM replacement kits if anyone wants to fork out the big bucks ($100-$150). There is a plug and play one where you simply mount the lights and plug them into the already mounted harness, or like me there is the kit that you have to run all the wiring plus install the fog light switch into the dash.

No worries, I didn't know there was an OEM kit available. I like this mod, but it's not worth that kind of money to me!

Exactly. My friends dad picked the kit up from the dealership and never used it so I bought it off of him. I have installed fog lights on several of my vehicles and although I love that it looks like it came out of the factory including the switch on the dash, I think it's too pricey and can be done just as easy like the way you did it. If anyone needs some help with the OEM kit feel free to message me and I'll try to walk you through it and supply some pictures. Thanks Musclemkeester for the write up, it definitely helpful regardless what kit.

Use your FOGS FOR DLRs

This one of my old post. It will work for what you want also.

I can help with running your fogs how you wish. I run my fogs all the time.

I have wired my factory fog lights to work as DRLs. The lights will work as factory fogs and/or as DRLs. They are at full power when on. I have up graded the bulbs. A small toggle switch in the dash controls a relay. In the off position, fogs work as normal with the headlights. In the on position, fogs come on with the engine, without the parking lights. The switch completes ground for the relay and is so you can turn the lights on/off as desired. I leave it on all the time. 4 diodes (watch polarity) keep the computer from knowing the difference. The relay, as always, gets power (fused) straight from the battery. The coil of the relay gets ignition on power from the fuse module #M35.
I hope you can under stand my wiring diagram.
I have been running this set up for over a year now, trouble free. I turn them off when I go to the dealer to stop questions.

great write up, Im not sure if it is "legal" or not in Ontario, from what I have read you need to have atleast 2 lights on at once and a maximum of 4, but considering you turn your high beams off for on coming traffic who cares how many lights you have on when no one is around... and as far as DRL's, drive around with your lights on.........
