I don't see anything necessarily wrong with the diagram but then some details are not included. The switch and relay internal connections are not shown but down below is how I would assume they are used. First of all, which wire(s) burned? Do you have this exact part number switch and socket with pins 83 and 83A on the back? If not, you may be shorting the B20 wire to the Brown wire whenever the switch is on and this would be an unfused short to ground and stuff would MELT, namely the wires to the switch and maybe the relay. If you do have this switch and socket, test as below.
1. Are switch pins 83 and 83A normally open and then connected together when the switch is on? 2. Does the relay pin that goes into relay socket 7 pin 1 correspond to the ground pin of the relay? 3. Does the relay pin that goes into relay socket 7 pin 4 correspond to the coil pick pin of the relay?
If the above are all true, you may need to look at your wiring. This is how I think it is supposed to work. Socket pin 1 = ground for relay coil Socket pin 2 = 12 volts in (from X circuit) to drive fog lights, only present when ignition on, key not turned to start( this is to turn the fog lights off automatically when starting). Socket pin 3 = 12 volts out to switch, if switch is on then to Fuse S6, and then to fog lights. Socket pin 4 = 12 volts in to enable/pick relay, only present when headlight switch is on, even if only to parking light position (signal 58). Use a volt/ohm meter to check. Put the relay in with no added wiring connected and see if the relay works and there is 12 volts at B20 only when the lights and ignition are both on. Mark
