Well look at the wiring as this.
You have a plug correct or the lights.
If you look at the socket you should have two or three wires. You need to find which one is power/ground.
Put the power wires together and run it to your switch.
Put the ground wires to a good engine ground.
The switch you will need to see what the constant 12v prong is, the switched 12v prong and the ground.
Ground it, find a suitable constant 12v in teh fuse panel that is open and then put the power wires on teh fogs to the switched 12v!
That should give you power. TO test this theory make a jumper wire for the power or just touch the fog lights to your battery to the proper ground/power wire.
