I don't include any antinieblas relay in the schemes that I have (Son of the Scenic), what appears to me is an electronic module located under the left steering wheel.
That is the interconnection module of the cabin and is more or less complex depending on the version.
I am going to pass the cable codes and connectors related to the anti-classes:
a gray-red cable enters a black connector in a crystal coloring by track No. 2, this cable comes from the control of flashing and steering wheel lights.
An orange cable and a black orange from a 17 -way blue orange, by the A7 road, the black orange Vá towards a brown connector by route 10 and is the witness light of the painting. The orange goes to a 14 -way black connector that is plugged into another black. The cable passes by the B6 of the black and A7 of it leaves two violet cables towards the front antinieblas.
A cable comes out that does not make me what color is of a blue 17 -path connector by the A3 road that is that of the rear fools.
I don't know how to tell you more because the schemes are not very clear either.
