Thanks Alex, some manufacturers use the same loom which would make it much easier in fitting.
There is an old thread about it here:-

Maybe my front ones don't have bulbs or maybe blown bulbs that's why they're not working?
My front fog light (right side) do not work and don't pas the MOT. Ask my local service dealer to replace both side bulbs. Got my car back, same problem, right side still don't work.
Return the car. Service reply, bad earthed. Next day, same problem.
If it was not properly earthed, I assume both fog lights would not worked? I believe the fog light wiring harness has a common ground? Can anyone confirm? Where is the fog lights wiring earthed? Any other pin points to look for?
