Actually, it you want fogs on with low and high beams, then set it up just exactly like I have it. The diode will allow you to turn on the Fogs with switch WITHOUT turning on the low beams. Then the low beams will turn on the fogs. And the quirk in the 2007+ is that the high beams turn on the low beams, which would then in turn turn on the fogs if you have the diode.
