I think Jim is right. I looked on Z Car Source to see what they had for switches. They do have a defroster switch, but it's obviously too small to fit in the hole on the right. I did look for Niles brand switches to help preserve the look. The search took me to ebay, where I saw this Nissan hazard switch: https://www.ebay.com/itm/115356499313?epid=20040619831&hash=item1adbc87d71:g:ovYAAOSw5BJiY1z6 On Amazon, I saw rocker switches like this: https://www.amazon.com/Position-Rocker-Toggle（Quality-Assurance-Years）KCD3-101/dp/B07MV56LKS The listing has lighted and non-lighted switches.

Please create a signature and put the year of your car in your signature. Different year cars had different consoles and switches.

Do you have voltage to ground at the middle fuse on the right? (Touch the positive probe of the meter to each side of the fuse to make sure you don't have a bad fuse.) No on voltage at the fuse? Do you have a good ammeter installed? Stop and fix before proceeding. (A disconnected or bad ammeter would cause both parking lights and headlights to fail.) Yes on voltage at the fuse? Check for voltage to ground at the headlight switch at the arrows. (See picture below.) No voltage at green/blue - Bad connection between fuse box and switch. No voltage at white/red - Bad connection between ammeter and switch Let's get that working, and then we can focus on the brake lights and turn signals.

The white/red wire that is loose should power the fuses boxed below. It should mount to a stud on the bottom side of the fuse box. (This explains your parking lights.) If you know how to use a multimeter (voltage and resistance testing), I can give you some diagnostics for the headlights. The brake light & rear turn signals could be the turn signal switch. Again, if you know how to use a multimeter, I can give you some diagnostics.

I had a chance to ride shotgun during the parade laps at the Mitty today. I think the HSR pace car driver is enjoying the gig.

The 6-pin connector doesn't look properly seated. You may want to take it apart and put it back together again. That could fix your running lights. For the headlights, there should be a black wire going from the turn signal switch over to the ground on the right side of the steering column. I didn't see that one.

I actually found a thermostat housing like the one @kully 560has - https://maseraticompound.com/products/datsun-240z-thermostat-housing

Yeah, that's not stock for a 73. As I mentioned before, the roadster belts could be installed in such a way that you won't have the belt retractor in the way.

This link may be cheaper. https://www.ebay.com/itm/154916677637?chn=ps&mkevt=1&mkcid=28

I improved my search by specifying AGC fuse holder. https://www.delcity.net/store/AGC-Adjustable-Fuse-Holder/p_800425.h_800426 Del City is reputable, and I have purchased from them.

A possible source for holders that aren't pre-wired. I have not done business with them. https://www.asi-ez.com/member/~PTF-80.asp?shop=y

Also, when I changed out the old seatbelts in my 260Z, I bought the roadster style seatbelts from Wesco Performance Products. https://www.wescoperformance.com/nsearch.html?query=roadster I put the retractor at the top mount.

That is not a stock retractor. The stock retractors fit in a pocket in the floor. Post a photo of the top mount.

Inline glass fuse holder. I can only find pre-wired ones now. I bought some on Amazon 4 years ago that were not pre-wired, but they are no longer available. 250V is the voltage rating. Since you have a 12 volt system, there isn't a problem.

It's Mitty weekend at Road Atlanta. I spent a few minutes with Greg Ira and Scott Hyatt in the paddock after their first qualifying session. Greg was top dog in that session. He may have shown his hand too soon.

Emissions testing would be real there.

If you want to come down this way, I think the Georgia Z Club is planning on going to the PoBoys Cruise In in Canton. I think that's a little over an hour and a half from you. The Cruise In is the 3rd Saturday of the month, and I think we're planning to show up in June.

The output is on the low side. What was the RPM for that voltage? What is the voltage at 2000 RPM?

I know what you were talking about. That's why I told you where you could source the correct size fasteners. https://belmetric.com/coarse-thread-jis-small-wrench-hex-nut-class-8-steel/? https://belmetric.com/coarse-thread-jis-small-wrench-hex-nut-class-8-steel/?sku=NJ8X12YLW (Yellow Zinc) I bought 100 of these.

By the way, if you want the 12 mm head M8 nuts and bolts(JIS spec), you can get them from Bel-Metric.

A friend of mine with over 30 years experience wrenching on Z cars doubles up on the gasket when installing headers. For instance on my L28, I had two Beck-Arnley gaskets with a generous amount of Ultra Copper to adhere the gaskets to one another.

I have been driving the 240Z so much lately that I wanted to take the 260Z out. You can't have them feeling neglected, right? There was a car meet half an hour away. I had the only Z, but it wasn't the only Nissan. There were a couple of JDM Skylines, a Roadster, and a GTR. (Does a G35 count? 😉 )

I'm just glad that you weren't somewhere underneath when it happened.
