i tried to do the fog on, off mod. I screwed up something, now my fog light doesnt work anymore. I followed the instruction step by step, but i think i messed up at the relay rewire part, i didnt follow the numbers on the diagram that BananaGs showed, stupid me. Also on the steering wheel foglight switch plug, its said that we should tap into that wire not unplug it right? anyone experience this b4 please help, thanks guy

i also took everthing back out and leave it as how factory would be, still not working, i check all the fuse it's still good and also the foglight plug in the front bottom bumper, there is not power comeout.

Yes. Tap the wire into the plug. that's probably your problem right there if you didn't do it.

recheck your wiring again.

well i actually stripped the wire and wrap the extension wire around it and black tape it up

check your fog relay again. Whenever attempting a DIY, always double check the wiring diagram. You might be lucky enough that you didn't damage anything.

It's a really easy mod, as long as you connect the right wires.

well i put everything back where they belong. I also use the headlight relay next to the fog relay see if it works, same thing not working. I also notice that when i turn on the healight, the headlight relay click, but when i turn on the foglight, the foglight repay no clicking.

so you put everything back to stock and it doesn't turn on still?

see if you can find the fuse for the fogs. The fuse is there to protect shortings.

the fuse for the fog is the 15a green color right under the foglight relay, i checked the fuse its still good, i also use the test light to test bothside off the fuse just to makes sure the testlight go on both sides.

i really appreciated GSteg for answering all my question bro,

It could be a lot of things. Perhaps complicated as wiring being melted off, or simple as a loose connection somewhere. If I was in MA, I'd help you out

Relays hardly die unless you run way too much power into it.

i'd like to see a result to this also. i bought a gs300 two weeks ago, and still haven't been able to figure out why my fogs don't light. fuses and relay work fine.

lexus wanted 105 bucks to diag the problem =/

There is one wire you have to ground. The BananaGS site wasn't 100% clear on some of the wiring details. I just remembered that I had the same problem when I attempted that mod the first time. Just look for the ground wire for the relay trigger and make sure it's grounded.

well b4 i even attemp this mod again i need to find out whats wrong with my foglight, i putted everything back, but its still not working.. I called my buddy, hes a Tech at my Lexus dealer, he said he gonna give me a print out of the foglight wire diagram, and also he will take a look at my car for me, we will find out....
