1. check if there is already wiring in place for fog lights.
2. connect the lights up to those wires, and then in the dash connect the wires there to a switch, or splice it onto the parkers wiring.
If you dont already have the wiring, then you need to run the positive to a switch in the car, and from the switch to the battery (+) and the negative of the lights to a good ground (either on the chassis somewhere or seeing as though they're pretty close anyway, just straight back to the battery).
That's how I would go about it . Only real problem I can see is where you will mount and fix the lights in the front bumper, but that's easy enough to work out.
