Have checked again Dave as well as looking at diagram link John posted above and advice is the same. Under the o/s front wheel arch should be a pair of blue/yellow wires 380mm from the point at which they break out of the main loom conduit running aft. Each of these wires should terminate in a male bullet probably protected and joined by a double female bullet connector. The second wire provides a loop to the n/s for that fog lamp.

My car is not on the ramp at the moment to confirm but recall seeing such wires doubled back and cable tied out of the way, but it was a while ago.

Not sure of the orientation of your pictures but below is one of the extra sidelight feed I needed for switchback LED bulbs. Hopefully you can place the area as top suspension cross arm is shown.

You can just see the bullet connector normally there for optional wingtop light and the short red wire I added to new three way connector. It would be worth looking in this area since your foglight wire should be in same grouping.
