To see if it is enabled on your car, you can jump pin 3 to pin 4 on the headlight switch connector D106. Pin 3 will be brown or green (depending on if you have the OEM alarm) and Pin 4 will be green.

Jump those wires and have the ignition on and the headlight switch in the low beam position. If the fogs don't light then the relay is not in there. For the 2nd gens for instance the integrated relay for the power windows and locks is not present on cars that were not built with them (and there are different part number for the body ECU).

Sorry stupid question: what do you mean by jump pin 3 to pin 4? Is that mean you connect the pin 3 to pin 4? just got a 2012 yaris hb le and want to add the fog light on. Thanks

With the 2012's to add fogs you simply install and connect the foglights on the front bumper and then install a switch that connects the wires in pins 3 and 4 together (i.e. jumps one wire to the other).

Remove the lower steering column cover.
Locate the connector shown in my picutre.
Tap the fog switch wires, one to the violet, and the other to the green wire.
The two by themselves.

You can alternatively not use a switch, and jump the two wires, they will go on, and stay on when the headlights are turned on.

Looks like I will be getting a micro image fog light kit......Toyota fog kit is warranty replace only. PLUS get this: parts department showed me on screen that mid level LE trim does not/can not have fog lights installed from factory or aftermarket.....lmao......he sighed and laughed too, as that is what the screen inventory stated.....

Yes. Besides Absolutely_Red, a few others have as well.

All that is needed from the kits, are the lamps, fillers, and switch.
2012s have the wiring preinstalled.
As CTSott mentioned, the relay is integrated into the BCM.
You dont even need a switch!! If you want the fogs to always be on with the headlamps.


The lamps, if anyone is interested, are Camry interchange part numbers!!

I for the life of me cannot find this. All that's below my steering column is an airbag? I'm a noob, little help please?

You are looking too far down. You need to remove the lower steering column cover to find that connector (which is at the base of the headlight switch).

Oh ok, is there a trick to taking it off? Or is it just the three screws and pop her off

Just the three screws and squeeze it by the seam to separate it.

I forgot to turn on the ignition DOOOOHHH!

Jumping the purple and green wires at 3&4 made the fogs go on!!
The light on the dash also works!!

Time to get some taps, and wire the switch.


Now taking this one step further, how do I make it work with park, low, high.

CT Scott, thank you for the help, also in advance!!

I'm sorry, but, I do not work. I have Yaris 1.4 d4d, 1ND-TV, I put the fuse, I jump the wires at 3 & 4 made ​​the fogs not go on! I started the engine and the fogs not go on. What can I do? Any idea?

[CTScott]

Jumping brown in 3 to green in 4 is correct for your TMMF built Yaris. The headlight switch must also be on and in low beam mode for the front fogs to light.

[geoded]

Yes, I did but it does not work.
