1998 peugeot 306 griffe 1.6 relays

I made a sound control circuit for my 1998 peugeot 306 griffe 1.6 vehicle, but I need help to install it on the vehicle. Where are the relays of these components? How can I reach them? I would be very happy if you could help.

My teacher, most of the controls are in the fuse box in the vehicle, in other words (bsi). For the exact scheme, it is necessary to research in foreign forums.
