Random Wire!?
Could be. Is the condenser there with a wire attached? If so, it's not that. My 1976 BCDD wire was black, I think. You might check the 1978 wiring diagram. The forum has some really nice color versions. https://www.classiczcars.com/files/category/1-wiring-diagrams/

At first glance I thought that was a smoky burnout picture. I knew somebody that put a 390 in one of those. Didn't last long.

COVID-19
I just noticed that your article was from the National Review. It fits. This quote is a good one. Not sure why they didn't use Hiroshima or Nagasaki for comparison. It could be worse! Be thankful. course, Sweden paid a price during the pandemic. But whatever price the Swedes paid for their COVID-19 policy, they will tell you it was worth it. And it is easy to figure out that price. They never cratered their economy or blocked nonemergency surgeries. They had more deaths than their Nordic neighbors, but nothing even close to the 650 deaths per million the U.S. suffered during the 1968 Hong Kong flu, a pandemic that was handled with few social-isolation controls and no lockdowns.

What's really interesting about Sweden's comments is that they are taking the "we're not the worst" approach. Italy and Spain, and the UK and France set the bar so low that everyone else can say "it could be worse". It's what the WH is doing now. The fact that old people and minorities are affected the most makes it easier for us younger and genetically favored people to see the "positive" side of things. More for us! We should set up an internment camp in the desert for the old people. https://en.wikipedia.org/wiki/Senicide https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/racial-ethnic-minorities.html?mod=article_inline

We need some kind of moniker for the "let the old people die" crowd. This is death panel stuff. Combine it with the broken food chain and we're in Soylent Green territory.

Poly Bushings for Transverse Link and Spindle Pin
Won't hurt it. It's just not a perfectly designed part. It's elastic plastic, not metal. It's probably going to get worn out and squished away over time anyway. I don't even know why they designed them that way, the factory bushings don't have rubber in that gap. If it were mine, I'd probably cut all of that flange away and fill the space with washers so it wouldn't be sloppy. The factory bushing uses the strength of the rubber to keep the part centered. By the way, you probably want to smooth those hammer marks down since that is a loaded surface at times. Those two surfaces slide on each other. Most of these PU bushings are not "engineered" for the application. They are just filling the space left over when the factory bushing is removed. Sorry, that's probably a big buzzkill but I think that it's true.

Random Wire!?
Sounds like the wire to the condenser/capacitor on the fender well. It would be hot when the key is on. See if the condenser is still in place, it's right across from the coil on the fenderwell.

240Z Distributor Questions
There is good stuff in the Service Manual. You should download it and look through the Tune Up chapter and the Engine Electrical chapter. Timing is set using a timing light. It's different from setting the gap of the points. It is normal for the rotor shaft to turn a few degrees. That is the mechanical advance mechanism working as it should.

Poly Bushings for Transverse Link and Spindle Pin
You might be able to hone out the bushing sleeves. I've used Scothbrite on the end of a suitably sized rod to hone things out. Cut s trip of Scothbrite, stick it over the end of the hole then jam it in with a rod on the end of a drill motor. Some WD-40 and a few million revolutions and the hole will get bigger. Surprising that the sleeve is too small. That's a bad product, since you have a new pin. Should be a perfect fit. Inside the casting, around the lock pin hole, there can be deformation. But I think you said that you already cleaned that up. The spindle pin should slide easily all the way through the casting hole.

New clutch...Noise when clutch is not depressed and trans in N?
This has the classic signs of noticing something that has always been there because you just did some work in that area. I had three different five speeds in my car that all made the bearing noise. Different sleeves, pressure plates, etc. but they all sounded about the same. Pedal down, noise gone; pedal up, noise there. Drive it for a few days and see if it changes. It will probably get a little louder when the oil is hotter and thinner.

Overall, the infection rate has been pretty steady, with the distancing and closures. Not really seeing a trend up or down or any reason to think it will go any way but up, in the near future, unless summer weather balances out the reopenings. https://www.mdmetrix.com/covid-19-projections

Poly Bushings for Transverse Link and Spindle Pin
You can see in your picture that the sleeve is narrower than the polyurethane bushing. People often just sand down the PU. But, as cgsheen1 implies, you can just compress the PU and squeeze it in there. It's elastic. Don't sand down any of the metal parts, it's only the PU that's a problem. I've used a thin paint scraper with lube on it to wedge the front bushings in to place. Use the thin piece of metal as a lubricated ramp to get over those edges. Once you get the edges started just squish it in there.

Dieing issue
That is odd. In order to create a spark the circuit through the coil needs to be completed then broken. It looks like the circuit is being "made" then being broken, maybe just due to overheating. I'm going to guess that your ignition module or the ignition coil is bad. When you turn the key on power flows through the ignition coil and the ignition module, something inside the module or the coil overheats and the circuit is broken, and a spark is created. It probably happens on #4 because the rotor just coincidentally was pointed at the #4 terminal in the cap. If you turn the rotor to a different spark plug you might get that plug to spark the same way. Feel free, anyone, to critique my guess. Since you already identified the coil as being out of spec. that's the easiest and cheapest part to try. If you have a spare coil of any type it will probably work for a test. If you want to try the GM HEI module there are some writeups on the site. It's just four wires and a place to bolt it to a good ground.

New clutch...Noise when clutch is not depressed and trans in N?
One of the bearings in the transmission is known for making noise. I think it's the countershaft bearing. Doesn't hurt anything it's just annoying. There are stories of replacing the bearing with a new one and have ing the nosie come back within a very short time. Might be why Nissan went to a bigger bearing with the 71C transmission. What kind of "some noise" is it?

Dieing issue
You should hear all six injectors click at the same time. It's very hearable when the engine is not running or the starter turning. It might be that your ignition system needs some work. I think that you said it used to start then die, now it doesn't start at all? Maybe recheck spark, then tune the ignition system if it's gone. Do you still have the original ignition module? It might be that it is dying also. 75 was only the second year of electronic ignition and the modules are very old now. You're pretty close I think. Reconfirm what used to be. If you have lost spark there are some cheap and easy ways to upgrade to a better more powerful ignition system using a GM HEI module. That module also got rid of the tachometer issue on my car. Stronger spark and no injection problems.

Dieing issue
Actually, you're way ahead of most people new to EFI (no offense to most people). You have a meter, you're using it, and you're getting real numbers. 1975 was the first year of EFI so Nissan's book wasn't the greatest. Here's a later one that has tests for all of the years up to 1980, and has better numbers, than "small resistance". You have to pick through and find your year but they give more info. Your 185 would be about 150 in the newer book. Close enough I think. I would focus on the Pin 1 signal. Is the tachometer still in the car? I've found that the whole circuit from the coil to Pin 1 needs to be intact for the ECU to open the injectors. Sometimes the system own't work if the tach is disconnected. There is a simple trick for checking the Pin 1 circuit that lets the ECU know when to open the injectors. Connect a wire to the coil's negative terminal. Turn on the key. Tap the other end of the extra wire to ground. You'll get a small spark as the coil circuit grounds. Every third tap should cause the injectors to click. That's what the ECU does, it counts sparks then injects.

Poly Bushings for Transverse Link and Spindle Pin
Resizing the bushing is pretty common. Some people manage to wedge them in there with some lube and some trickery. Here's one thread that mentions it. It starts out on the other end, loose, but ends up at tight. There are other posts about the issue on the site, try some search words in the box at the top of the page.

Just wait... Edit - I overlooked the first part of your comment. You're forgetting, maybe, about The Wall. Defense money was moved over to finance a few extra miles.
