Does anybody know which colored wire is the daytime running lights? Or does anybody have the diagram? I have just installed my fogs and want to tap into the daytime lights. Thanks in advance!!

If nobody tells you how to do it for free. You can get the answer here. It will cost $15 for 48hr access, but it has all the tech documents you will need.

Post up when you are finished, as I am thinking about getting the fogs for my F Sport and would like to know how you did it.

If you have a voltmeter you could find out.

The DRL will dim at night so I'm sure you don't want your fog light dim too.

I finally got the fogs to work. Pretty easy install once you know what you are doing. Now waiting on my Piaa plasmas!! I had a set of Piaa fogs laying around from years ago that I never used, so I took the wiring harness and installed it with the OEM fogs and jdm covers. I might be the only one in the Seattle area with a F sport with fogs!!

Awesome - got any pics?

I was also thinking about using a foglight kit and doing the same thing. Do you have the specific info about where you tapped in?

Mixman

Since you may be the first DIY guy with the fogs, then help the rest of us out with some directions !

Ok, so as long as you have the wiring harness for foglights, you are all set. Tapping the power line to the parking lights was a bit difficult to do at first b/c I didn't want to take off the bumper and so I was reaching underneath the car. First, you have to remove the white harness that connects to the headlight.

The wires to tap is pin # 17 or 19 (green in color). This wire will power on when your parking lights or headlights are turned on. (not the daytime running lights). Then put everything back together.

I put the switch inside the cabin right under the parking brake. Only the driver who's looking for it will see it. the parking brake light and the switch light match in my opinion.

This whole mod cost me roughly $125. I'm super happy as it looks OEM. Thanks to Nigel_JDMParts for the covers. I bought a set of aftermarket fogs on ebay and switched it off with my wife's venza so I have OEM fog light housing

Mixman

Thanks for the write up.....Great job! How long did it take to do from actually putting the fogs in the housing to wiring it up with the switch?

alex206

Probably about a good 4 hours, but a lot of it was figuring out which wire to tap and stuff. The actual install w/o power was about an hour.

This is good information.

Now I'm thinking to use this so I won't need to run a wire through the firewall.

It would really be cool to find out the pin outs to the OEM luxury stalk is to find the fog switch.

Mixman

Good find. I could tap into the pins Alex mentioned and be able to switch on and off without running wires into the cabin. In all honesty I would probably keep the fogs on with the lights 90% of the time anyway.

Another question,

When you mounted the fog lights did you use all 4 mount points? I read somewhere that only 2 are used. If so which ones were they? I'm seeing a bunch of used lights but some of the tabs are missing.

alex206

It was only 2 mounts on each side. Both on the top. In all honesty, going thru the firewall wasn't hard. There's a rubber plunge that I found that slips in real easy. Took me less than 10 min to install the switch from inside thru the firewall.

Which REMOTE WIRING HARNESS you guys bought? Any feedback? Decides not to run wires through firewall. It's a headache to run wires through Lexus firewall!
