The wires go through the firewall along with the huge factory batch.

The funny thing is that the set that I got is NOT the one that's shown in the item description!! The wiring is different. It is like the set that Peregrine's instructures describe ( http://www.pl-us.com/ACURA/JDM_FogLights.pdf ).

you can go to imageshack.us and upload the pic and paste the link here, or if you prefer, you can send the pics to supraken@hotmail.com and then I'll upload them... Thanks!

Is yours a US-spec TSX? Mine's a US '05.Also, I don't know if there's a separate LED on the switch, but it would be cool to have an indicator that the lights are on. I'll look into that too....
But I think the red wire is supposed to connect to "dash light brightness controller", which I think is ground with some resistance, and resistance changes depending on how you set your brightness.
But then again, I wouldn't worry about it.

Well, let me attempt that first, before I break out the duct tape...

Mine is a US '04 TSX.
There IS an LED light on my switch, and the switch looks pretty good.
I can also turn the fog lights with high beam of with no headlights at all (only parking lights). And the switch "remembers" its position (it clicks in when you turn fog lights on).
Good luck!

For those with factory fog lights, that want to have the fogs on independent of the headlights, I have come of with this. We now know that the blue and black striped wire under the factory fog light rely will turn on the fog lights if grounded. It other words, if we attach a wire from the body of the car and connect it to this rely wire, the fogs will come on. Problem is, we need a way tof control when the fogs come on, otherwise they will just come on everytime we start the car. Of course we need a switch of some type to turn this ground on and off.
Solution: I purchased a switch for a 2004 Honda Accord, along with the wire harness.( I want this to look factory). The switch will fit right in the blank plate where the sunroof switch is. Next I bought a second relay. This relay will be controlled by the new honda foglight switch to turn the fogs on and off. What I am going to do, is use the parking light hot wire, to power the second relay,so that when I turn the parking lights off, the fogs will go off too. If you want the fogs to be available"on " at anytime, just use any "hot wire that is hot" when the car is turned on.
So now, when I turn on my parking lights, this will power my new switch, which will then, turn on the second relay(when I depress it), that will connect the blue and black striped wire to ground.
If you still want to use the regular fog light stalk, it will work the same when you turn off your new switch. If you turn both on at the same time, nothing happens other then the new switch will always bypass the factory one. I hope this is clear, and I plan to get started on this, this weekend. Hopfully I will have some pictures.
This same thing could be accomplished with just the factory switch if someone could identfy the wires coming from our that switch. You would still need that second relay. I hope this is clear.

Matvey: Thanks again for the great find. My foglights arrived today. Turns out, the instructions (labled "Honda Accord 2003") specifically mention the connector under the fusebox being held on by blue tape. Sure enough, I can look under there and there it is! Wow. I guess it's not used for the USDM fogs, but for some reason it's still in the wiring. Go figure.
Looks good, now I just need time to do the install. I figure it'll take a few hours.

While you guys are messing around with all those wires... could you check some voltages on some of them while you're in there? I'm having a hard time getting my factory fogs to work. My post is here https://acurazine.com/forums/showthread.php?t=33675.

Finally got my 06 tsx fogs to work independently of the headlights switch. Not hard to do, but not a job for the novice. You will have to get a seperate rely and another switch. It is the Only way to do it right. The way I rewired it, the fogs will come on with the parking lights, since I used the hot from it to power the second relay. This also means if I leave the fogs on, they will cut off automatcally, when the parking light do.
I have the fog light switch from the 94 honda Accord which fits the tsx dash. I also bought the wire harness as well to make for a neat installation. Hardest part was getting to the parking light hot wire, and that was not bad at all. I will post pictures once I finish up everything. This mod does not affect the factory stalk switch. The dash button will overide the stalk, but if you leave the dash switch off, the stalk works as normal. There is not problem if both are on at the same time, as both switches do nothing more, than connect ground.

If you have problems, make sure that you've got a GOOD ground. (On my previous car, I think I had to find a different connection; the easiest/closes bolt didn't work. I found a more inconvenient bolt, and it worked great.) If the ground doesn't work, the bulbs won't light....

It can be done
Finished up the fog light mod for 06 tsx. Picture is fog lights on with parking lights and Honda fog switch. The original swich on the stalk still works the same. There is no problem using both. The dash switch will override the factory switch when the parking lights are on. If the headlights are on, both swiches will work.

I did buy the switch harness. It makes the job easier. You will also have to buy a seperate rely. It is not plug and play. Not very hard to do, and you do not need the honda switch. You can use any switch you want. You can even wire it with no switch and have the fogs come on once you turn the parking light on, but they would always be on until you cut the car off or the parking lights go off. I think total I paid $75 for everthing. The switch is from a 94 honda Accord

Hey Supraken,thanks for those pics.I already have my fogs worked out thanks to Peregrine,but i would really like to get the switch illumination set up.I cant seem to find that female grey connector you posted up in the first pic.Can you be more specific about where to find it under the dash.Is it above or below the fuse box,is it on a loom somewhere deeper under the dash above the pedals,is it part of a block of connectors???Its so frustrating not being able to find it.Any help appreciated.

Ok,so I got impatient and went looking again for that connector.If its in my car i cant find it.My guess is our Aus cars are different to yours in that area.Anyway i wanted to hook up my switch so that the light icon illuminates when the dash lights are on.
The little green indicator light above the light icon already works when the fogs are turned on but I couldnt find a wire on the back of the fog switch that when connected to a live feed would light up the icon on the front of the switch.Then i remembered reading on here somewhere that the original equipment Honda fogs switch on by grounding the earth.So i figure thats possibly how the switch illuminates as well...sure enough,when i connect that red wire that everyone says is not used for anything, up to an earth..hey presto the switch light icon lights up when i turn on the parking or headlights.
Still not there yet,because while it lights up, it wont dim with the rest of the dash lights.Got to find some connection somewhere that operates this circuit.
Now if i could only find that damm grey connector socket!!

Simple. There should be a red white wire coming from your other switche(VSA is one) Tap your red white from your foglight switch to it. That is the wire that controls the brightness.

Aw doh !! why didnt i think of that.Of course youre right 'dwest1023'.
I was so pissed off at not finding that grey connector i overlooked the obvious and easiest connection point for a wire linked to the dimmer circuit,Thanks for that.I might tackle that little job next weekend.

Fog light mod update
I have just recieved my tsx service manual. I have found a way to have the fog lights on anytime you want, with the original fog light switch. There is a white wire, that come sfrom the fog light switch connector, which then runs to the engine compartment to the relay control module. This module is located in the fuse relay box under the hood. All you need to do, is connect a wire to this white and then over to the blue/Back in the wire harness under the fog relay. I like my method better with the seperate switchand relay, cuz the fogs will cut off when I turn the ignition off. The method I describe above, will allow the lights on with engine off or running. . If anyone would like to see the wiring diagram I can post it.

As you can see, in the 06 tsx the ground connection that turns our fogs on is controlled by the relay control module. located under the hood. If you attach a wire to the white wire, coming from our stalk switch, to the blue black, under the fog light relay, you effectively bypass the module. Thus you can now turn on the fogs when ever you want. Hope this is clear.

In my experiences with VW's, folks used to just replaced the relays with little metal clips (in the same configuration as the relay) to allow for fog use with parking lights and/or high beams. Several vendors sold the clips which were a couple $'s at most.

Hey dwest1023,just as a matter of comparison,could you tell me how much in your dollars did your manual cost you.Honda dealers over here want $800, which is about $600US.Its a bloody rip-off of course,but i guess it stops the peasants getting too knowledgeable.The last Honda manual i bought 5 or 6 years ago cost me 70bucks.

Hm... ok... expected to see at least one response. Oh well... Anyhow, I figured it all out after about 3 hours of fiddling. One last question for you guys out there.... (hope this one gets answered...) Apprantly my ebay fogs didnt come with the screws that go into the adjusting mechanism. So I cant adjust the aim of my fogs. Anyone know where I can get those screws? I dont know if the guy I got these fogs from will send me any.

I just worked on the fogs yesterday, so I've got it 1/2 done.
To unlock the 20-pin connector, you need a really small screwdriver, but sounds like you finally got it. I fiddled with this for at least 20 minutes.
Weird, my fogs came preinstalled with the adjusting screws. However, I seem to be missing the screw that goes underneath to secure it (right next to the adjusting screw). Either that, or I used the screws that were supposed to go there on something else.

I'm revisiting this older message, as I have some additional comments (having done the engine wiring).
I did too, although, there were instructions that came with the fogs (for a "2003 Accord"!) that mentioned grounding to the hood hitch. Those bolts were in tight, so I'm going to try using the hitch-cover, with a bolt from the kit.
I have not gotten to the under-dash part yet...
In addition to the location, it looks like they have put blue tape at this location as well, so it's pretty easy to find. However, the harness connector does not match this connector! Even though they are a similar shape and color, they don't fit.
So, I disassembled the harness connector and plugged just the green wire into the car's plug, on the side with the green wire. It still has the flat edge connector on the end, so I didn't have to redo anything, just pull it from the connector (using a small screwdriver to help). I have not tested whether or not this will work, as I haven't gotten under the dash or done the interior harness yet.
Is this what you did, Matvey, removed the green wire from the plug in order to fit?
Yeah, the harness just BARELY fits in the front too, but no rewiring needed! Some assembly require, tho.

Except the following:
1. I did not extend the ground wire that is between the left and the right fog light. I have attached it to the hood hitch/lock.
2. I did not cut off the 2-pin connector (green and red wires), instead I have plugged it into a grey 2-pin plug under the dash. They were made for each other! perfect fit.

Since I had an extra wiring for the TSX, I figured out that the under-the-hood grey plug leads directly to the under-the-dash grey plug, the one that gets connected to the fog light switch.

OK, the fogs are mostly done. I have run into a couple of snags.
First, I will say that the plug in the engine does seem to lead to the plug under the dash. However, the harness plugs did not sync up! The under-hood harness was the wrong size; I had to disassemble it and plug the green wire in separately. Under the dash, the plug that was the correct size had the wrong wire (red). I disassembled both plugs and put the green wire into the plug that fits. Yikes!
After that fiasco, the fog lights do turn on! And since I didn't use the red wire, the illumination does not dim, but the illumination does work. The fogs turn on if the parking lights (or main lights) are on.
The worst problem is that the switch illuminates in amber color. Everything else on my dash is green. Gaaaah......
So, right now, my main goal is finding an appropriate dimmer wire to splice into.

The worst problem is that the switch illuminates in amber color. Everything else on my dash is green. Gaaaah......
So, right now, my main goal is finding an appropriate dimmer wire to splice into.

Well, my harness(es) are different than what Dwest described. I don't have any red/white wires in my foglight harness, but I do have two red/black ones. I disconnected those, one at a time, to see if they affected the illumination, but it seems like cutting either of them kills the entire switch. And the red wire doesn't do anything. It's late, so I give up! I guess the illumination isn't that important; maybe I should look into getting a US switch.
Also, in case anyone was confused by my previous message, my harness seems to be different than some others in that on the under-dash harness, the green wire was in a 3 pin plug that didn't fit anything, and the red wire was in the 2-pin plug that I reused.
