The 1 position fog light switch only switches the front foglights, not rear ...
If you wanted to use the 2 position switch, you would have to modify it because when it's in position 2, position 1 is also on ... so in turn if you wired the driving lights on pos. 2, your regular foglights would also come on when they are turned off ... I dunno if I'm making much sense, but you'd probably get pulled over for too much light unless you modify the switch to have independent turn on/off.
edit: remove the connection between the 2 positions, then run a relay that would switch foglights off when the driving lights come on and vice versa.
