Bookmarked thank you! You dont by chance have the pinout for this BA2 connector do you? I am not going with the OEM stalk or even a button switch install, BUT I would like a convenient place to tap or insert my trigger wire so that the fogs come on with the parking lights under the hood in a weathertight place if at all possible.
Little more digging turned up this in regards to DRL lights being the trigger for the fogs. I do wonder if this will be a problem if halogen fogs are used though. I would still pull power from the battery but would use the middle wire of the LED daytime running lamp adapter found below the headlight as my trigger.
After years of contemplating I have decided to buy this kit from iJDMTOY. I ideally would like the fog lights to only come on with the headlights but would that draw too much power? If not which wire should be used to T-Tap?
Was it decided that the 14-18 gauge T-Tap should be used for the green wire?

I know this is a super old thread but I had to say thank you because I just purchased OPT7 LED AURA Underbody Lighting Kit and could not find how to get the wires inside the car. Your detailed explanation on how to get to and through the firewall is a life saver!!!
For those who want a stealthier switch install location you can use the toggle switch style and mount it inside the coin pocket as shown here with double sided tape: Attachment 427516
is there a way to access the coin pocket without drilling?
2. Locate and remove these plastic plugs (11) in order to expose the area on top of the headlights and radiator. Lift and remove the passenger headlight smaller plastic section. Then remove the larger plastic cover on top radiator.
Here the red lines indicate roughly where you will run your harness and a single trigger (parking light) wire into the cabin. Here's a quick summary don't worry I'll go more into details later:
Near the battery you will attach your harness Relay, Ground, and Positive power source. Route shorter end of harness toward front passenger fog area. Then continue the longer end of the harness across the bottom in front of the radiator toward the driver side fog. Then run the single long Trigger wire back toward the engine firewall and into the cabin to your switch. Then attach your switch ground. Finally tap the parking light power source in the cabin to your switch and you're set!
3. So here near the battery corner, unbolt a nut at R and mount your harness Relay. Below and to the right locate another bolt (G) with multiple ground wires attached. Use this to connect your harness Ground wire. At this point you can attach your harness Power wire (has an inline fuse) to the Positive battery terminal. I actually didn't do this until the last step of the fog install. Just don't forget to come back if you choose to do this.
4. Run harness down passenger side of fender. I actually wrapped the harness with black electric tape to keep an OEM look. Run shorter end of harness into passenger fog light area. I'll show you how to get access to the fog light later.
5. Now run longer part of harness in front of the radiator. You can secure the harness using double sided tape and zip tie. Continue running the longer part of the harness across the radiator to the driver fog light area. We'll come back to finish this part later.
6. At this point there should be a final single longer wire that needs to be routed into the cabin and connected to your switch. Run this Trigger wire (red arrow) up the driver side of fender toward the firewall of the engine.
7. When you're at the engine firewall on the driver side. Remove this plastic cover. There are two different plastic clips. Remove the first one like the previous 11 clips in the beginning. The second clip in a plug in so just lift up. Finally release tab closest to firewall and lift cover out.
8. Now notice where this metal stick is pointing. That is where you will be looking for a rubber grommet. You want to run your Trigger wire through this and into the interior cabin. Since this is much easier if done from inside the car. The next step will show you how.
9. From inside your car on the driver side. Get down and look right above the dead pedal. You will see this black round grommet. Get something like a coat hanger and poke a hole through this area (red circle). Now go back to the engine side and try to secure your trigger wire to that hanger (probably the second most difficult part of the install). Then pull the coat hanger and Trigger wire through the rubber grommet into the cabin.
Now get your switch. It will have three connections. First is ground, second is parking light power, and we'll call the third "Trigger". Connect the Trigger wire you just pulled in from the engine to this wire.
10. Under the big round grommet above you will find a good Ground point (red square). Attach your switch Ground wire here. Now you will have the last remaining parking light power source. We'll do that next.
11. To tap the parking light power source you first need to remove this plastic panel under the knee airbag sign (3 screws and 2 clips) on the driver side.
13. On the harness you need to locate this green wire (red arrow). This is the parking light power source that needs to be connected to your switch. The fog light only turns on when the parking lights are on. Here you can see the parking light wire already being tapped by red wire. This was the most difficult part of the install!
14. Now you can mount the switch where ever you like. I mounted my switch between the seat cooler buttons with double sided tapes. Some people mount them under the dash or on the dash somewhere.
15. Now we turn your attention back to the fog light areas in the bumper. Turn the steering wheel toward one side for easier access to the wheel wells. Remove two plastic clips and one or two screws from under the bumper. Lift fender lining out of the way to route the harness/ plug and install the fog bezels and lights.
16. Here's what it should look like after removing the OEM F Sport bezel (4 clips) and install your JDM fog lights and bezels. Again you only need to screw the two bottom screws. Leave the top two taps unsecured, don't worry it's pretty tight.
If you haven't done so attached your fused positive wire to the battery and test our your new fog lights!! They should look something like this. Don't worry I'm testing out two bulbs that's why the colors are different

@Neophyte2b – Which bumper tabs are you referring to? Once you remove the top plastic pieces, the two additional pop-plugs (what I call the plastic plugs that fasten the underhood plastic covers down) near the headlights, and remove the plugs and bolt in each wheel well, you can pull the bumper off (after removing all the screws along the underside, of course).
For the wiring, the best option I found was the parking light wire. It is in the cabin, under the dash in the driver's kick panel. Pull the lower dash panel off (3 screws and 2 pinch clips) and then I also found it useful to pull off the panel above it (under steering wheel). Remove the side panel with the driver door open, and remove the radio surround, and then you can pull the middle panel (below steering wheel) off.
The wire is against the fender to the left of the dead pedal / footrest. It's a white plug with several wires – the green one on the top row (first one closest to you on the top row) is the one you want. It's a huge pain in the *** to tap, but once you have the remote trigger wire tapped into that, the fogs will turn on with the parking lights, which gives you the ability to run them with your DRLs (no headlights) or with everything.
I don't have pictures myself, but the pictures ARE in other threads – that's how I learned.
The entire job is a pain. It looks amazing, but it's a pain I don't recommend. Good luck.
As requested by those who wants to install fog lights in their F Sports using a generic switch. This is a really fun weekend project and I think you'll enjoy it as well.
1. Toyota fog lights (2) PN 81210-0D042* (R) and 81220-0D042* (L)
*Ok to use 41, and 40 (last 2 digits) part numbers. Toyota uses these same fog lights in many of their cars. They update their parts number every few years even though it's the same part.
4. A high quality fog light harness and switch. I got these on fleabay (search title below). I like the harness but I ended up not using the switch. I liked the push button one better, just personal preference.
WIRING HARNESS 4 CATZ HELLA PIAA BOSCH KC FOG LIGHTS
5. Optional switch. I didn't like the switch above so I purchased a PIAA push button switch. It is a push button and allows you to stick it any where you want without drilling a hole.
I'll post the rest of the instructions later when I get a chance.
I know that this is an old thread, but... Where does the Putco Harness go? Are you splicing it to the end of the Catz Harness to the blue and black wires?
