DIY yaris III fog lights installation

[karloslatynos]

I went through al lot of data available here about fog lights installation but most of it is related only to yaris II generation. The 3-rd one electric system looks a little bit different.

I have purchased aftermarket duolight multi - function (DRL + fog lights) kit.

That product is dedicated to convert already existing fog lights system to duolight one. As my european (french made) yaris have not been equipped with fog lights, I am looking for more information how to install them (fog lights only as DRL looks dead easy to connect)

The way I wanna do it is to replace the indicator/headlight stalk with only rear fog light switch to front & rear one (like Bairjo did https://www.youtube.com/watch?v=bilhPerqVEo)
That is the stage where actually I haven't got a clue how to move forward...

- is the front fog light wire present in the indicator/headlight harness?
- where do I plug-in the relay?
- where do I connect the wires to the fuse box under the hood?

Someone gave me an idea of not to change the indicator/headlight stalk & connect the front fog lights to the rear one, so they both can be switch on at the same time. Is it possible to do it?

BTW the manufacturer suggested to connect the DRL yellow wire to the parking lights. I want to be cheeky and have my DRL lights switch off only when the front fog lights are operating.
