wiring up driving lights and fog lights for idiots please.

[vwvirgin]

Ok, so when you read this I can deal with the dimwit and halfwit jibes provided I get an answer, Have fitted me lights have wired from the lights to there respective relays have earthed the relays and bought the wiring single blue inside the camper. under dash. I would like the driving lights to come on via main beam, the fog lights separate to a switch on the dash.
Each light has an earth . Right questions, can I earth all the lights to the same point where should I pick up the power from How do I link the driving light to main beam. If this lot makes me look thick its because I am, so many thanks and I will buy you a pint if you get me through this promise. Regards to all you type 25 ers. and as a moot point was so disappointed with the volksworld show anybody would think that type 25's were made by rover.
