ok had the same problem with mine.
you should find a switch down next to the headlight heigh adjustment, it will be labelled 'I' and 'II'. 'I' will select the 'fog' lights integrated into the main headlight, 'II' will select the ones down in the bumper.
behind the headlight/indicator stalk is a small cut-out that youll need to remove, they unlplug (hopefully not cut) this for compliance. plug it back in.
in the bumper, mine was only disconnected, i replaced the lights and plugged them back in and they worked.
it was the bit behind the switch that stuffed me up.
with yours, if they have cut the wires, just replace them. there is a harness that goes from the bumber fog lights towards the drivers side into the main engine harness. check for any cuts and replace wires.
if youre in sydney and want to compare to mine, ill be taking my front bar off this week to install an FMIC. or i or anyone probably wouldnt mind having a look at your car. there are a few aero selections kicking around now
