Your car should have the wiring under the bonnet for it ...if it does it will have the 2 pin plugs that go to the lights themselves taped back near both the head lights and the relay base and relay under the relay/fuse cover.
This is the diagram for the wiring under the bonnet The wire that is violet /red ( I think I called it pink/ red in this diagram by mistake ..it should be violet red) but it should be there that goes from the relay base through the firewall to the dash connector plug. You need to run a wire from the plug to the switch and tee off existing wires to fog switch connector above .
heres the diagram for it
This is the
diagram for the wiring at the dash plugs beside the fuses inside the car.The wire that comes from the relay is the violet/red wire on connector 124.Ignore the wiring connection directions as thats for installing a L3 dash . I have put this in just to show you the dash wiring connectors .
Another thing I found is the connector you need to install that plugs into the fog switch itself is the same in size and type as the air cond switch one.
If you get stuck I could make up the wiring with the plugs you need from spare stuff I have here .You have to make a few tee solder wiring connections as in the second diagram.
This
thread might be a help too.
