Hmm! a lot to take in there. Unused wires you may have found:
Purple and black wires terminating in female spade connectors are optional map light connections. Beware purple is permanently live.
Single red/orange also terminating in female spade and routed from cigar lighter - guessing this is panel light fed illumination for same.
2 x 8 way connectors - radio hook up if you don't have one fitted.
A little sceptical regarding fog light wires. Was expecting you to find the 8 way connector shown in Rog's picture with just the two wires mentioned. Can I take it you haven't found such?
Regarding switch you have top left. It has the icon for front fog but it's not clear on your pics if you have similar rear fog switch which I would expect to be top right. This should have similar icon but with beam lines sloping downwards. Can you confirm?
In any case I would suggest finding blue/yellow wires under front wings and hooking those up to your fog lights with suitable ground connections as discussed. This will give you the opportunity for testing at the dash end. Given your findings so far it could be they simply work with switch found
