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.

OK - The 3rd gen European Yaris is wired differently than the US market ones are, but they are pre-wired for front fogs.

The front fog light relay is not built into the body ECU, but rather is in a separate, small two relay box under the dash.

There is a 15A fuse (FOG FR) in the under dash fuse panel for them.

On the headlight switch connector, the green and brown wires are for the front fogs. Green gets connected to brown (ground) to turn on the fogs.


On the headlight switch connectors the light green wire is for the rear fogs. It too gets connected to the brown wire to turn them on. So you could simply jump green to light green to have the rear fog switch turn both on.
