What kind of switch do you have and test with a volt meter, each wire coming from the car to see what is ground and what is power and what goes to you fog lights.

Usually you will have 4 wires - two for the switch and two for the light. This assumes that the switch controls a relay and not the lights directly.

Use an ohm meter and find out which two contacts go to 0 ohms when the switch is on and connect those two wires to the swtich.
