Here is a grab from the BRZ Electrical Manual. We need to complete the wiring to the actual fog lights. The wiring is already in the harness currently in the car but rather than digging through the harness under the hood I chose to run two new wires to the fog lights.
In the schematic above everything shaded in blue is internal to the BCM. We need to tap into the connection points pin 3 and pin 5 of connector C3.
The BCM and this connector are behind the panel under the steering wheel. You remove the panel to the left side of the dash and remove one screw there. There is another screw to the bottom right of the panel that needs to be removed Then the panel just pops loose.
Here is a schematic of the BCU and the location of the pins we are tapping into.

so is nigels harness useless for this route?
