HOW DO YOU FIT FRONT FOG LIGHTS ON A 2002 MK3 FORD MONDEO ?

I HAVE RECENTLY PURCHASED AN 02 FORD MONDEO 2.0 LX TDDI & I WOULD LIKE TO FIT THE FRONT FOG LIGHTS TO IT.
I NEED A NEW LIGHT/FOG LIGHT SWITCH,FOG LIGHTS & THE WIRING LOOM.
WHERE DOES THE WIRING/CONNECTOR FROM THIS GO?
DOES IT GO STRAIGHT INTO THE BACK OF THE NEW LIGHT/FOG LIGHT SWITCH OR IS THERE PART OF THE WIRING LOOM IN THE ENGINE BAY WHERE IT NEEDS TO BE CONNECTED.
THANKS MARCUS
