could be from the gearbox, 1st gear switch for hdc or reverse gear switch?

Thanks for the response but my HDC is working just fine, and my autobox too. The connector block is just laying there unconnected

I have attached a few more photographs. The connector lies between the electrical connector box and the left hand wing and is behind the fuse box. It was dragged up to take the close up photo although the wire to the connector restricts it from being withdrawn any more.

It's not a spare O2 sensor plug, although similar in shape. The TD4 has a different engine bay harness to the V6, so wouldn't be wired for O2 sensors to start with.
I've not got round to looking at my TD4 yet. But from memory, I'm sure I have the same spare plug on mine too. Presumably it for something that's fitted as an option.

I already have a factory fitted FBH, but it could be for aux lights I guess as I don't have front fogs or driving lamps.
that’s ruled that one out then, assume it’s all working and not left unplugged , lol
only other thing i can think ref , aux lights , i bought a oem fog and spot light wiring loom and for the life of me i can’t remember the colour of the connectors
will try and see if i still have the wiring instructions

I know what you mean. I can't think of an option that would use a connector like that.
Fogs are wired right to the bumper corners and the HFS has a different colour plug. Besides, if I have the same spare plug, then the HFS wouldn't be hanging about doing nothing.
What are the colours of the wires. Maybe knowing that will help identify the circuit?

I'm thinking it could be something to do with the PCT heater fitted to some models.
W/P is part of the fuel pump circuit.

I do believe you have it right. I was coming to a similar conclusion myself after reading the electrical spec (part attached) and I cannot think of any other option that would have provision made in a standard loom.
I don’t think I’ll be searching eBay for a second hand PCT though .....

i had Pct fitted on my 2002 td4, was fitted just above the heater matrix inside the cab
noticed it when i had to replace my leaking heater
at least @Nodge68 was able to identify the aux lights position, for the life me i couldn’t remember

The spare connector in question is part of the PCT heater circuit, the rest of which isn't fitted or needed if the FBH is fitted.
That's why I also have the same connection floating about. It might be handy to power some auxiliary circuits though, like DRLs for instance.

Yes it could come in handy for some goodies installed aftermarket, though I like to keep my cars pretty much as supplied. Hence why I still have my EGR and crankcase breather filter. I guess I’m just a Luddite at heart.
that makes sense ref the ptc / fbh
good idea as u say being able to pinch that connector for some drl lights
must admit i always found in the winter the cabin got nice and warm , only reason i knew the ptc heater was there when i had to take all the dashboard out, all good fun , lol
