Things needed – standard relay (4 pin)
Access your BCM, to do this remove the passenger side hush panel, the BCM is the black box with a lot of wires coming out.
Connector C1 (gray, 16 pin) locate pin A4, (they are labeled) it’s a dark green/white wire. This is the BCM control wire for the fog lamp relay. i.e. when this wire has a ground the fog lights go on.
Connector C3 (pink, 24 pin) pin A4 is a orange wire. This is the wire coming from the stock fog light switch. When the switch is closed this wire has a - charge.
Cut these two wires. At this point you could connect the two wires and it would work, but we want to ignition control this so we don’t leave our lights on.
Take pin 86 of the relay (pins are labeled on the side of relay) and connect to ground.
Connect pin 85 to a switched 12 volt source. A good spot would be the sunroof fuse in the fusebox on that side of the car. Don’t worry if you don’t have a sunroof, you’ll still have the fuse and its functional.
Connect the orange wire (not the end coming out of the BCM) to pin 87 of the relay.
Connect the dark green/white wire (again not the end of the wire coming out of the BCM) to pin 30 of the relay.
Tape off the wires you cut coming out of the BCM with electrical tape.
You will now have independent operation of your fog lights whenever the car is on.

I followed these instructions and it is real easy to do.
I found it easier to connect the wires to the relay by using spade connectors on the wires. (I already had these at my house, but they aren't need to complete the mod).
