'70 Series II engine bay wiring harness --

I have purchased a new engine bay wiring harness for my restored Series II. According to the SNG Barratt catalog, it is the correct part number for a Left hand Drive Series II (part #JL-202).

Unfortunately when I looked at the bonnet bulkhead connector from the old harness, I noticed that it had seven wire connections versus the new harness which only has six. All my wiring diagrams from the factory manual and from every Jag site that I could find shows only six connections.

This is the connector in question -- shown is the original connector with seven wires. The extra wire in question is the larger gauge wire that is connected to the #6 bonnet bulkhead plug connector.

This is the wire that isn't found on the newly purchased harness.....

...... and is connected top the #6 plug pin.

The original wiring diagram shows only six connections -- and no mention of this #6 wire. It looks like the wire color was originally white with a very thick red tracer swirling around it -- or red with a thick white tracer -- not sure at this point due to color fading

Has anyone run across this problem with their cars? I should mention that this car has power brakes and AC.

Any help would be appreciated.
 
I have tried to attach (failed!)a pic. showing the redundant wire ( red/yellow trace) which is listed in the wiring code as supply fog lamp etc.

Regards,

That Red/Yellow wire is for fog lamps. Generally unused, it was just there for someone who chose to add them.

The other end of that wire is behind the drop-down center panel:

And here you can see it (connected to nothing) inside the bonnet:
