First of all, use a relay! It is crazy to run all of that current through a switch. Second, I will tell you how I wired my driving lights. It is the best way in my opinion. My driving lights just come on with the high beams only. There is not even a switch for the driving lights. You can't have them turned on any way unless there is no oncoming traffic. I just wired the relay signal wire power to the high beam headlight wire.
