wiring fog lights

[hummer05]

i have the basic piaa set up
two plugs go into the fog lights then that wire goes into a relay, then the wire goes to the pos and neg of the batter directly, then the wire goes to a on/off switch, but right before you get there there is another wire breaking off called the switch wire that i assume is suggested to plug into the driving lights/parking lights ectt area so that they will not be on unless the driving lights or parking lights are on (at night to avoid battery drain)
now i went out there and plugged it into the area that powers the parking lamps when i did that with the key off i got juice to the new fogs and they worked
as soon as i turn the key on l lose power to the fogs completely, it is like the opposite of what should be happening.
