rear fog light does not work

There is a Peugeot Partner 1.6 HDI of 2006 with 9hx motor code that does not work on the antiniebla, we have checked all the wiring that goes from the pilot to the gray trailer plug, there it combines in blue and then rises again to the pilot's area where in another clabijero, it becomes brown and the code code is 201 g, and my question is again. color, where does it go and have any fuse out there? Because in the few schemes that I have, he says that the left pilot comes out in 201 G would then come together with 201 D that would be the one on the right that in this case does not exist and would reach the fuse box in the 201 cable and does not put any fuse.
Please help me.
