1970 Wiring Diagram

There's an empty hole in 1971, then there's a Nissan factory labeled cigar lighter in 1973 in the exact same spot.  About as far from bizarre as a logical person could get, I think. 

That's what's known as confirmation bias. The "empty hole" was designated for the optional E4100 fog lamp switch, as I have already pointed out. The E4100 fog lamp switch - literally - could not go anywhere else. The design of the switch alone dictates that.

They should have put that information in the Owners Manual, instead of just showing an empty hole.  Beside that, do you have any documentation describing the optional fog lamp switch?  And the fog lamps, which, of course, would need installation also.  That would add a lot to the discussion.  Much more interesting than a single comment in a forum.  The details and official documentation.

Sorry for the "single comment in a forum" (hopefully you can't see my eyes rolling....). I'm writing this after you have posted a couple of old threads - active several years before you joined the site - which discussed the factory fog lamps in some detail, with a fair chunk of the posted data coming via Yours Truly. I suggest you spend a little time actually reading and understanding it. There's gold in them thar hills...

Here's a different guy that says the fog lamp option was Japan market only.  So if that's correct then Nissan was basically cutting costs by not producing non-Japan market dashes.  They just left the spot open with no option for non-Japan market customers to fill it with anything.

 

But he is - of course - mistaken. The other option is that he knows full well that the factory fog lamps were offered in markets other than the Japanese domestic and - get this - he's trying to sell you something. It wouldn't be the first time that somebody stretched the truth a little - or didn't manage to tell the whole truth - when telling us about these cars. Does "Made Expressly For The USA" ring any bells...? 

Here's a scan of a page from Nissan's 'R-Drive' Export market parts catalogue C-0010R. The components are - just like they were in Japan - listed as 'Option' parts:

 

We could - indeed we have, back in the days when this forum was a little bit more engaged by matters historical than in reading spark plug runes - discuss many other monkey tail appendixes and "mystery" (to some more than others...) holes and fixtures on these cars that are there for a very good reason.

As for the factory Fog Lamps, the component parts existed, the wiring was there in the harness to run them, the mounting points were pre-drilled in the front bumper to accept them and the indentation and doubler was there on the dash to accept the switch, from October 1969. Yes, they moved the Cigar Lighter up there later. Doesn't mean that they wanted it there all along.

Unless they got creative, with something like an F knob.

I think the problem here is that you have come up with a theory and are now engaged in shaping evidence so that it fits. Sorry but your 'F Knob' theory isn't even going to float, let alone fly.

Alan are you able to translate item 17. I'm guessing "optional fog light switch" 🙂

Indeed, it translates as "Fog Lamp Switch" and other factory literature identifies them as being an extra-cost showroom option.

Thanks Alan, just for fun I tried using the translate feature on google lens. It worked well.
