DIY : F-Sport fog light retrofit
Fogs and yellow Lamin-X arrived today, so I wasted no time getting it on while I am here at the office. The wiring harness and JDM grills are from Nigel-jdmparts
Not my image, but OEM F Sport fog grills
Car they will be going on:
Popped one in to see
There are actually 2 screws and one tab so overall points it is secured.
I didn't want to tap or destroy any factory wiring in case, so here is what I did for my trigger wire to work with parking lights. It is actually a strand of wire from a coaxial cable that I clipped and soldered to the multistrand trigger wire then heatshrinked. I also pushed the wire into the weatherproof boot a tad more but forgot a pic so it's actually fully inside the boot now.
Now when I unlock the car with my fob, the parking lights, LEDs and the fogs now come on which is nice for dark parking lots. Also, for those that need to ensure the fogs go off with high beams, I read that you can run your relay ground and tap it to the high beam signal which is probably in that 24 pin headlight connector. That way when they are flashed it will remove the ground to the relay and therefore shut the fogs off.
On the 24 pin headlight connector image below, 17 and 19 are the parking lights and both are green wires. 8 is headlights and is a red wire and 18 is the DRL's which has power on ignition and parking lights but when headlights are on it does not which is why it makes sense not to use that as a trigger unless you use multiple relays and have drl OR hl as the trigger.

You can get an OEM JDM stalk with an independent fog switch and swap that on BUT it's a lot more work and cost. I figure since I always like to run fogs anyway I will use my DRL LED's as their trigger or if that doesn't work when I test then I will wire my trigger to be my parking lights. In either case they will.be able to be tuned on and off with the current stalk though.

Nice I am doing the same thing my boy is wrapping mine this week, I was thinking about wiring up the same to a separate switch that will get power with the parking lights, so that may I can drl's only, drl's and fogs, or headlights and fogs

Good call. All depends on how you want it to work. I want them on all the time while driving which is why DRL as my trigger is what is desired. If I want them off, I can toggle the stalk to DRL off and then they will be off.

Unless the law has changed in Virginia don't forget that fog lights can't be used at the same time when using bright lights.

I wonder if the DRL's go off when you flash your high beams. If so then this setup will work. I'll have to have my kids flash the highs while I watch tonight.

If definitely has not changed lol... I dislike how VA laws limit what you can do to our cars. Tinted window restrictions, no radar detector, mandatory front plate...blah blah blah, I usually get around the fog light thing with the inspection by temporarily just taking the bulbs out... If the lights have a bulb in it and don't work you can fail, but as long as there no bulb in.. It passes...

No progress on fogs today. Will finish wiring tomorrow. I did notice that in the splash shield Lexus put 2 holes which are in the perfect spot to change a fog bulb if needed with no trim removal
I did also add about 15 hp with some caliper decals though
