Frank it is but 2 points--he says his are faded and many times the wire appears orange--he obviously does not have a wire chart and the size of the wire suggests heavy current. So what do you think it is to help him?

The heavy current may imply fog lights, George – rather than some sensors, which draws little current...
Wiring diagrams are sort of useless for physical tracing unless the wire colours can be read – and as you rightfully comment, fading is certainly a problem after this long time. Jaguar was very consistent in the use of wire colours; same colours were used throughout for the same items – colours added when new items were added.
So *’dark; red/yellow* was used throughout for fog lamps as they were introduced as an option – prewired, though not that often fitted ex factory. If the wire colours found do not match the diagrams, in this case fogs, it’s a different circuit – and we cannot exclude that. Or that these wires have been added by a PO for some reason or another...
One possible explanation for the the location of this wire end, near the bulkhead, is that it has been pulled out from the separate fog light switch on the dash. This switch may or may not be in place ex factory, but as far as I recall, room was left for such a manual switch – with wiring in place. Explaining the rather thick wire, as it would be dimensioned to carry current to both fogs...
As suggested; the actual fog wires should be in place near the bumpers - to be located for final identification. Whether the search is worth while depends on if he wants fogs – or just plain, legitimized inquisitiveness as to mystery wires...which may or may not be fog wires...
