Radio, clock, interior lights not working
 

I have a Trajet 2003.. trying to fit a car stereo...suddenly the clock has stopped working along with radio, central locking and interior lights.. I'm told this is something to do with the permanent live wire.. have checked a few fuses.. all fine.. does anyone have a fuse box diagram for the fuse box under the steering wheel? also another guy online said he fiddled with the relay controller A.. does anyone know where that is? cheers
